MAKING OF Iphone

I phone

 

  iPhone is a line of smartphones designed and marketed by Apple Inc. They run Apple's iOS mobile operating system. The first generation iPhone was released on June 29, 2007; the most recent iPhone model is the iPhone 7, which was unveiled at a special event on September 7, 2016. The user interface is built around the device's multi-touch screen, including a virtual keyboard. The iPhone has Wi-Fi and can connect to cellular networks. An iPhone can shoot video (though this was not a standard feature until the iPhone 3GS), take photos, play music, send and receive email, browse the web, send and receive text messages, follow GPS navigation, record notes, perform mathematical calculations, and receive visual voicemail.

Other functions—video games, reference works, social networking, etc.—can be enabled by downloading mobile apps. As of June 2016, Apple's App Store contained more than 2 million applications available for the iPhone. Apple has released ten generations of iPhone models, each accompanied by one of the ten major releases of the iOS operating system. The original 1st-generation iPhone was a GSM phone and established design precedents, such as a button placement that has persisted throughout all releases and a screen size maintained for the next four iterations. The iPhone 3G added 3G network support, and was followed by the 3GS with improved hardware, the 4 with a metal chassis, higher display resolution and front-facing camera, and the 4S with improved hardware and the voice assistant Siri. The iPhone 5 featured a taller, 4-inch display and Apple's newly introduced Lightning connector. In 2013, Apple released the 5S with improved hardware and a fingerprint reader, and the lower-cost 5C, a version of the 5 with colored plastic casings instead of metal. They were followed by the larger iPhone 6, with models featuring 4.7 and 5.5-inch displays. The iPhone 6S was introduced the following year, which featured hardware upgrades and support for pressure-sensitive touch inputs, as well as the SE—which featured hardware from the 6S but the smaller form factor of the 5S. In 2016, Apple unveiled the iPhone 7 and 7 Plus, which add water resistance, improved system and graphics performance, a new rear dual-camera setup on the Plus model, and new color options, while removing the 3.5 mm headphone jack found on previous phones. The iPhone's commercial success has been credited with reshaping the smartphone industry and helping to make Apple one of the world's most valuable publicly traded companies by 2011.

The original iPhone was one of the first phones to use a design featuring a slate format with a touchscreen interface.Almost all modern smartphones have replicated this style of design. In the US, the iPhone holds the largest share of the smartphone market. As of late 2015, the iPhone had a 43.6% market share, followed by Samsung (27.6%), LG (9.4%), and Motorola (4.8%).

HISTORY 

Development of what was to become the iPhone began in 2004, when Apple started to gather a team of 1000 employees to work on the highly confidential "Project Purple",including Jonathan Ive, the designer behind the iMac and iPod.

Apple CEO Steve Jobs steered the original focus away from a tablet, like the iPad, and towards a phone. Apple created the device during a secretive collaboration with AT&T Mobility—Cingular Wireless at the time—at an estimated development cost of US$150 million over thirty months. Apple rejected the "design by committee" approach that had yielded the Motorola ROKR E1, a largely unsuccessful collaboration with Motorola. Instead, Cingular gave Apple the liberty to develop the iPhone's hardware and software in-houseand even paid Apple a fraction of its monthly service revenue (until the iPhone 3G)

IPHONE 3gs

in exchange for four years of exclusive US sales, until 2011. Jobs unveiled the iPhone to the public on January 9, 2007, at the Macworld 2007 convention at the Moscone Center in San Francisco. The two initial models, a 4 GB model priced at US$499 and an 8 GB model at US$599 (both requiring a 2-year contract), went on sale in the United States on June 29, 2007, at 6:00 pm local time, while hundreds of customers lined up outside the stores nationwide The passionate reaction to the launch of the iPhone resulted in sections of the media dubbing it the 'Jesus phone'.[ Following this successful release in the US, the first generation iPhone was made available in the UK, France, and Germany in November 2007, and Ireland and Austria in the spring of 2008. On July 11, 2008, Apple released the iPhone 3G in twenty-two countries, including the original six.Apple released the iPhone 3G in upwards of eighty countries and territories.Apple announced the iPhone 3GS on June 8, 2009, along with plans to release it later in June, July, and August, starting with the US, Canada and major European countries on June 19. Many would-be users objected to the iPhone's cost, and 40% of users had household incomes over US$100,000.HThe back of the original first generation iPhone was made of aluminum with a black plastic accent. The iPhone 3G and 3GS feature a full plastic back to increase the strength of the GSM signal. The iPhone 3G was available in an 8 GB black model, or a black or white option for the 16 GB model. The iPhone 3GS was available in both colors, regardless of storage capacity. The iPhone 4 has an aluminosilicate glass front and back with a stainless steel edge that serves as the antennas. It was at first available in black; the white version was announced, but not released until April 2011, 10 months later.

IPHONE 4

Users of the iPhone 4 reported dropped/disconnected telephone calls when holding their phones in a certain way. This became known as antennagate. On January 11, 2011, Verizon announced during a media event that it had reached an agreement with Apple and would begin selling a CDMA iPhone 4. Verizon said it would be available for pre-order on February 3, with a release set for February 10.In February 2011, the Verizon iPhone accounted for 4.5% of all iPhone ad impressions in the US on Millennial Media's mobile ad network. From 2007 to 2011, Apple spent $647 million on advertising for the iPhone in the US On Tuesday, September 27, Apple sent invitations for a press event to be held October 4, 2011, at 10:00 am at the Cupertino Headquarters to announce details of the next generation iPhone, which turned out to be iPhone 4S. Over 1 million 4S models were sold in the first 24 hours after its release in October 2011. Due to large volumes of the iPhone being manufactured and its high selling price, Apple became the largest mobile handset vendor in the world by revenue, in 2011, surpassing long-time leader Nokia.American carrier C Spire Wireless announced that it would be carrying the iPhone 4S on October 19, 2011. In January 2012, Apple reported its best quarterly earnings ever, with 53% of its revenue coming from the sale of 37 million iPhones, at an average selling price of nearly $660. The average selling price has remained fairly constant for most of the phone's lifespan, hovering between $622 and $660.The production price of the iPhone 4S was estimated by IHS iSuppli, in October 2011, to be $188, $207 and $245, for the 16 GB, 32 GB and 64 GB models, respectively. Labor costs are estimated at between $12.50 and $30 per unit, with workers on the iPhone assembly line making $1.78 an hour. In February 2012, ComScore reported that 12.4% of US mobile subscribers used an iPhone. Approximately 6.4 million iPhones are active in the US alone. On September 12, 2012,

I PHONE 5

Apple announced the iPhone 5. It has a 4-inch display, up from its predecessors' 3.5-inch screen. The device comes with the same 326 pixels per inch found in the iPhone 4 and 4S. The iPhone 5 has the SoC A6 processor, the chip is 22% smaller than the iPhone 4S' A5 and is twice as fast, doubling the graphics performance of its predecessor. The device is 18% thinner than the iPhone 4S, measuring 7.6 millimetres (0.3 in), and is 20% lighter at 112 grams (4 oz). On July 6, 2013, it was reported that Apple was in talks with Korean mobile carrier SK Telecom to release the next generation iPhone with LTE Advanced technology On July 22, 2013, the company's suppliers said that Apple is testing out larger screens for the iPhone and iPad. "Apple has asked for prototype smartphone screens larger than 4 inches and has also asked for screen designs for a new tablet device measuring slightly less than 13 inches diagonally, they said. On September 10, 2013, Apple unveiled two new iPhone models during a highly anticipated press event in Cupertino. The iPhone 5C, a mid-range-priced version of the handset that is designed to increase accessibility due to its price is available in five colors (green, blue, yellow, pink, and white) and is made of plastic. The iPhone 5S comes in three colors (black, white, and gold) and the home button is replaced with a fingerprint scanner (Touch ID). Both phones shipped on September 20, 2013. On September 9, 2014,

IPHONE 6

Apple revealed the iPhone 6 and the iPhone 6 Plus at an event in Cupertino. Both devices had a larger screen than their predecessor, at 4.7 and 5.5 inches respectively. In January 2015, "Apple stands on second slot i.e only 31% in US market". Competing devices with Android operating system have a market share approximately 62% of the US, 82.7% of the Chinese market, and 73.3% of the European market (countries such as the UK, France, Germany Spain and Italy). In 2016, Apple unveiled the iPhone 7 and 7 Plus,

which add water resistance, improved system and graphics performance, a new dual-camera setup on the Plus model, new color options, and remove the 3.5 mm headphone jack. 


HARDWARE 
SCREEN AND OUTPUT 

The touchscreen on the first five generations is a 9 cm (3.5 in) liquid crystal display with scratch-resistant glass, while the one on the iPhone 5 is 4 inches.The capacitive touchscreen is designed for a bare finger, or multiple fingers for multi-touch sensing. The screens on the first three generations have a resolution of 320×480 (HVGA) at 163 ppi; those on the iPhone 4 and iPhone 4S have a resolution of 640×960 at 326 ppi, and the iPhone 5, 640×1136 at 326 ppi. All iPhones were and still are equipped with LCDs. The initial models were using twisted-nematic (TN) LCDs. Starting with iPhone 4, the technology was changed to in-plane switching (IPS) LCDs. The iPhone 5 model's screen results in an aspect ratio of approximately 16:9. The touch and gesture features of the iPhone are based on technology originally developed by FingerWorks. Most gloves and styli prevent the necessary electrical conductivity; although capacitive styli can be used with iPhone's finger-touch screen. The iPhone 3GS and later also feature a fingerprint-resistant oleophobic coating. The top and side of an iPhone 5S, externally identical to the iPhone 5. From left to right, sides: wake/sleep button, silence switch, volume up, and volume down. The iPhone has a minimal hardware user interface, featuring five buttons. The only physical menu button is situated directly below the display, and is called the "Home button" because it closes the active app and navigates to the home screen of the interface. The home button is denoted not by a house, as on many other similar devices, but a rounded square, reminiscent of the shape of icons on the home screen. However, the Home button on iPhones with Apple's fingerprint recognition feature Touch ID (which use the Home button as the fingerprint sensor) have no symbol. A multifunction sleep/wake button is located on the top of the device. It serves as the unit's power button, and also controls phone calls. When a call is received, pressing the sleep/wake button once silences the ringtone, and when pressed twice transfers the call to voicemail. Situated on the left spine are the volume adjustment controls. The iPhone 4 has two separate circular buttons to increase and decrease the volume; all earlier models house two switches under a single plastic panel, known as a rocker switch, which could reasonably be counted as either one or two buttons. Directly above the volume controls is a ring/silent switch that when engaged mutes telephone ringing, alert sounds from new & sent emails, text messages, and other push notifications, camera shutter sounds, Voice Memo sound effects, phone lock/unlock sounds, keyboard clicks, and spoken autocorrections. This switch does not mute alarm sounds from the Clock application, and in some countries or regions it will not mute the camera shutter or Voice Memo sound effects. All buttons except Home were made of plastic on the original first generation iPhone and metal on all later models. The touchscreen furnishes the remainder of the user interface. A software update in January 2008 allowed the first-generation iPhone to use cell tower and Wi-Fi network locations trilateration, despite lacking GPS hardware. Since the iPhone 3G Generation, the iPhone employs A-GPS operated by the United States. Since the iPhone 4S generation the device also supports the GLONASS global positioning system, which is operated by Russia. The iPhone 6S and 6S Plus, introduced in 2015, feature "force-touch" displays which allows the screen to recognise how hard it is being pressed. An example of how this technology will be used is lightly pressing the screen to preview a photograph and pressing down to take it. 

sensors

Latest iPhone devices feature seven sensors, which are used to adjust the screen based on operating conditions, enable motion-controlled games, and location-based services. 


PROXIMITY SENSORS 

A proximity sensor deactivates the display and touchscreen when the device is brought near the face during a call. This is done to save battery power and to prevent inadvertent inputs from the user's face and ears. 


AMBIENT LIGHT SENSOR 

An ambient light sensor adjusts the display brightness which saves battery power and prevents the screen from being too bright or too dark. 


ACCELEMENOTER 

A 3-axis accelerometer senses the orientation of the phone and changes the screen accordingly, allowing the user to easily switch between portrait and landscape mode. Photo browsing, web browsing, and music playing support both upright and left or right widescreen orientations. Unlike the iPad, the iPhone does not rotate the screen when turned upside-down, with the Home button above the screen, unless the running program has been specifically designed to do so. The 3.0 update added landscape support for still other applications, such as email, and introduced shaking the unit as a form of input. The accelerometer can also be used to control third-party apps, notably games. It is also used for fitness tracking purposes, primarily as a pedometer. 


MAGENOTOMETER 

A magnetometer is built-in since the iPhone 3GS generation, which is used to measure the strength and/or direction of the magnetic field in the vicinity of the device. Sometimes certain devices or radio signals can interfere with the magnetometer requiring users to either move away from the interference or re-calibrate by moving the device in a figure 8 motion. Since the iPhone 3GS, the iPhone also features a Compass app which was unique at time of release, showing a compass that points in the direction of the magnetic field. 


GYROSCOPIC SENSOR 

Beginning with the iPhone 4 generation, Apple's smartphones also include a gyroscopic sensor, enhancing its perception of how it is moved. 


RADIO 

The iPhone contains a chip capable of receiving radio signals, but Apple has the FM radio feature switched off, citing lack of demand as users have switched to data-streaming apps. 


FINGERPRINT SENSOR 

The iPhone 5S, 6, 6 Plus, 6S, 6S Plus, SE, 7, and 7 Plus feature Apple's fingerprint recognition sensor,

which is located on the Home button. 


AUDIO AND OUTPUT 

From left to right is the headphone jack, microphone, Lightning connector, and built-in speaker on the base of the iPhone 5S. On the bottom of the iPhone, there is a speaker to the left of the dock connector and a microphone to the right. There is an additional loudspeaker above the screen that serves as an earpiece during phone calls. The iPhone 4 includes an additional microphone at the top of the unit for noise cancellation, and switches the placement of the microphone and speaker on the base on the unit—the speaker is on the right. Volume controls are located on the left side of all iPhone models and as a slider in the iPod application. The 3.5mm TRRS connector for the headphones is located on the top left corner of the device for the first five generations (original through 4S), after which time it was moved to the bottom left corner The headphone socket on the 1st-generation iPhone is recessed into the casing, making it incompatible with most headsets without the use of an adapter. Subsequent generations eliminated the problem by using a flush-mounted headphone socket. Cars equipped with an auxiliary jack allow handsfree use of the iPhone while driving as a substitute for Bluetooth.



The iPhone 7 and 7 Plus have no 3.5mm headphone jack and instead headsets must connect to the iPhone by Bluetooth, use Apple's Lightning port (which has replaced the 3.5mm headphone jack), or (for traditional headsets) use the Lightning to 3.5mm headphone jack adapter, which still plugs into the Lightning port. Apple's own headset has a multipurpose button near the microphone that can play or pause music, skip tracks, and answer or end phone calls without touching the iPhone. Some third-party headsets designed for the iPhone also include the microphone and control button. The current headsets also provide volume controls, which are only compatible with more recent models. A fourth ring in the audio jack carries this extra information. The built-in Bluetooth 2.x+EDR supports wireless earpieces and headphones, which requires the HSP profile. Stereo audio was added in the 3.0 update for hardware that supports A2DP. While non-sanctioned third-party solutions exist, the iPhone does not officially support the OBEX file transfer protocol The lack of these profiles prevents iPhone users from exchanging multimedia files, such as pictures, music and videos, with other Bluetooth-enabled cell phones. Composite or component video at up to 576i and stereo audio can be output from the dock connector using an adapter sold by Apple. IPhone 4 also supports 1024×768 VGA output without audio, and HDMI output, with stereo audio, via dock adapters. The iPhone did not support voice recording until the 3.0 software update. Battery Replacing the battery requires disassembling the iPhone unit and exposing the internal hardware The iPhone features an internal rechargeable lithium-ion battery.


WORKING OF IPHONE.

 

Like an iPod, but unlike most other mobile phones at the time of its launch, the battery is not user-replaceable The iPhone can be charged when connected to a computer for syncing across the included USB to dock connector cable, similar to charging an iPod. Alternatively, a USB to AC adapter (or "wall charger," also included) can be connected to the cable to charge directly from an AC outlet. Apple runs tests on preproduction units to determine battery life. Apple's website says that the battery life "is designed to retain up to 80% of its original capacity after 400 full charge and discharge cycles"which is comparable to iPod batteries. The battery life of early models of the iPhone has been criticized by several technology journalists as insufficient and less than Apple's claims.This is also reflected by a J. D. Power and Associates customer satisfaction survey, which gave the "battery aspects" of the iPhone 3G its lowest rating of 2 out of 5 stars. If the battery malfunctions or dies prematurely, the phone can be returned to Apple and replaced for free while still under warranty The warranty lasts one year from purchase and can be extended to two years with AppleCare. The battery replacement service and its pricing was not made known to buyers until the day the product was launched it is similar to how Apple (and third parties) replace batteries for iPods. The Foundation for Taxpayer and Consumer Rights, a consumer advocate group, has sent a complaint to Apple and AT&T over the fee that consumers have to pay to have the battery replaced Since July 2007, third-party battery replacement kits have been available at a much lower price than Apple's own battery replacement program. These kits often include a small screwdriver and an instruction leaflet, but as with many newer iPod models the battery in the first generation iPhone has been soldered in. Therefore, a soldering iron is required to install the new battery. The iPhone 3G uses a different battery fitted with a connector that is easier to replace. A patent filed by the corporation, published in late July 2013, revealed the development of a new iPhone battery system that uses location data in combination with data on the user's habits to moderate the handsets power settings accordingly. Apple is working towards a power management system that will provide features such as the ability to estimate the length of time a user will be away from a power source to modify energy usage and a detection function that adjusts the charging rate to best suit the type of power source that is being used The iPhone 4 is the first generation to have two cameras.

LED FLASHING OF IPHONE

The LED flash for the rear-facing camera (top) and the forward-facing camera (bottom) are available on the iPhone 4 and subsequent models. Camera The 1st-generation iPhone and iPhone 3G have a fixed-focus 2.0-megapixel camera on the back for digital photos. It has no optical zoom, flash or autofocus, and does not natively support video recording. (iPhone (original) & 3G can record video via a third-party app available on the App Store, and jailbreaking also allows users to do so.) IPhone OS 2.0 introduced geotagging for photos. The iPhone 3GS has a 3.2-megapixel camera with autofocus, auto white balance, and auto macro (up to 10 cm). Manufactured by OmniVision, the camera can also capture 640×480 (VGA resolution) video at 30 frames per second, although unlike higher-end CCD-based video cameras, it exhibits the rolling shutter effectThe video can be cropped on the iPhone and directly uploaded to YouTube, MobileMe, or other services. The iPhone 4 introduced a 5.0-megapixel camera (2592×1936 pixels) that can record video at 720p resolution, considered high-definition. It also has a backside-illuminated sensor that can capture pictures in low light and an LED flash that can stay lit while recording videIt is the first iPhone that can natively do high dynamic range photography.The iPhone 4 also has a second camera on the front that can take VGA photos and record SD video. Saved recordings may be synced to the host computer, attached to email, or (where supported) sent by MMS. The iPhone 4S' camera can shoot 8-MP stills and 1080p video, can be accessed directly from the lock screen, and can be triggered using the volume-up button as a shutter trigger. The built-in gyroscope can stabilize the image while recording video. The iPhone 5 and iPhone 4S, running iOS 6 or later, can take panoramas using the built-in camera ap and the iPhone 5 can also take still photos while recording video. The camera on the iPhone 5 reportedly shows purple haze when the light source is just out of frame, although Consumer Reports said it "is no more prone to purple hazing on photos shot into a bright light source than its predecessor or than several Android phones with fine cameras...On all five model generations, the phone can be configured to bring up the camera app by quickly pressing the home key twice On all iPhones running iOS 5, it can also be accessed from the lock screen directly. The iPhone 6S and 6S Plus are outfitted with 12 megapixel camera, with 4K HD video capability. Just as well, the user may change the resolution between 4K and 1080p from settings. The iPhone 7 features Optical Image Stabilization on its rear camera, and the 7 Plus is the first iPhone to feature dual-lens camera (both 12 MP), and they both have a 7 MP front-facing camera. The second camera on the iPhone 7 Plus is a telephoto lens, which enables 2x optical zoom and up to 10x digital zoom. The rear cameras on the 7 and 7 Plus are both f/1.8 aperture. Storage The iPhone was initially released with two options for internal storage size: 4 GB or 8 GB. On September 5, 2007, Apple discontinued the 4 GB models. On February 5, 2008, Apple added a 16 GB model.The iPhone 3G was available in 16 GB and 8 GB. The iPhone 3GS came in 16 GB and 32 GB variants and remained available in 8 GB until September 2012, more than three years after its launch. The iPhone 4 was available in 16 GB and 32 GB variants, as well as an 8 GB variant to be sold alongside the iPhone 4S at a reduced price point. The iPhone 4S was available in three sizes: 16 GB, 32 GB and 64 GB. The iPhone 5 and 5s were available in the same three sizes previously available to the iPhone 4S: 16 GB, 32 GB, and 64 GB. The lower-cost iPhone 5C model was initially available in 16 GB and 32 GB models; a 8 GB model was added later. The iPhone 6 and 6S are available in three sizes: 16 GB, 64 GB, and 128 GB. The iPhone SE is available in 16 GB and 64 GB variants. By the time the iPhone 7 and 7 Plus was released, Apple ditched the based model from 16 GB to 32 GB as the base storage. Both 7 & 7 Plus has a configuration of 32, 128, & 256 GB storage option. And Apple also doubled the storage on the iPhone 6s & 6s Plus in 2 configurations (32 GB & 128 GB). SIM card An iPhone 5S with the SIM slot open. The SIM ejector tool is still placed in the eject hole. GSM models of the iPhone use a SIM card to identify themselves to the GSM network. The SIM sits in a tray, which is inserted into a slot at the top of the device. The SIM tray can be ejected with a paper clip or the "SIM ejector tool" (a simple piece of die-cut sheet metal) included with the iPhone 3G and 3GS in the United States and with all models elsewhere in the world. Some iPhone models shipped with a SIM ejector tool which was fabricated from an alloy dubbed "Liquidmetal". In most countries, the iPhone is usually sold with a SIM lock, which prevents the iPhone from being used on a different mobile network. The GSM iPhone 4 features a MicroSIM card that is located in a slot on the right side of the device. The CDMA model of the iPhone 4, just the same as any other CDMA-only cell phone, does not use a SIM card or have a SIM card slot. An iPhone 4S activated on a CDMA carrier, however, does have a SIM card slot but does not rely on a SIM card for activation on that CDMA network. A CDMA-activated iPhone 4S usually has a carrier-approved roaming SIM preloaded in its SIM slot at the time of purchase that is used for roaming on certain carrier-approved international GSM networks only. The SIM slot is locked to only use the roaming SIM card provided by the CDMA carrier. In the case of Verizon, for example, one can request that the SIM slot be unlocked for international use by calling their support number and requesting an international unlock if their account has been in good standing for the past 60 days.This method only unlocks the iPhone 4S for use on international carriers. An iPhone 4S that has been unlocked in this way will reject any non international SIM cards (AT&T Mobility or T-Mobile USA, for example). The iPhone 5 and later iPhones use the nano-SIM, in order to save more space for internal components. 


LIQUID CONTACT INDICATORS

All iPhones (as well as many other devices by Apple) have a small disc at the bottom of the headphone jack that changes from white to red on contact with water; the iPhone 3G and later models also have a similar indicator at the bottom of the dock connector Because Apple warranties do not cover water damage, employees examine the indicators before approving warranty repair or replacement. The iPhone's indicators are more exposed than those in some mobile phones from other manufacturers, which carry them in a more protected location, such as beneath the battery behind a battery cover. The iPhone's can be triggered during routine use, by an owner's sweat, steam in a bathroom, and other light environmental moisture Criticism led Apple to change its water damage policy for iPhones and similar products, allowing customers to request further internal inspection of the phone to verify if internal liquid damage sensors were triggered Included items The contents of the box of an iPhone 4.

LIQUID CONTACT INDICATORS OF IPHONE

From left to right: iPhone 4 in plastic holder, written documentation, and (top to bottom) headset, USB cable, wall charger. All iPhone models include written documentation, and a dock connector to USB cable. The first generation and 3G iPhones also came with a cleaning cloth. The first generation iPhone included a stereo headset (earbuds and a microphone) and a plastic dock to hold the unit upright while charging and syncing. The iPhone 3G includes a similar headset plus a SIM eject tool (the first generation model requires a paperclip). The iPhone 3GS includes the SIM eject tool and a revised headset, which adds volume buttons (not functional with previous iPhone versions). The iPhone 3G and 3GS are compatible with the same dock, sold separately, but not the first generation model's dock.All versions include a USB power adapter, or "wall charger," which allows the iPhone to charge from an AC outlet. The iPhone 3G and iPhone 3GS sold in North America, Japan, Colombia, Ecuador, and Per include an ultracompact USB power adapter. 


SOFTWARE 

The iPhone, iPod Touch and iPad run an operating system known as iOS (formerly iPhone OS). It is a variant of the same Darwin operating system core that is found in Mac OS X. Also included is the "Core Animation" software component from Mac OS X v10.5 Leopard. Together with the PowerVR hardware (and on the iPhone 3GS, OpenGL ES 2.0), it is responsible for the interface's motion graphics. The operating system takes up less than half a gigabyte. It is capable of supporting bundled and future applications from Apple, as well as from third-party developers. Software applications cannot be copied directly from Mac OS X but must be written and compiled specifically for iOS. Like the iPod, the iPhone is managed from a computer using iTunes. The earliest versions of the OS required version 7.3 or later, which is compatible with Mac OS X version 10.3.9 Panther or later, and 32-bit Windows XP or Vista. The release of iTunes 7.6 expanded this support to include 64-bit versions of XP and Vista, and a workaround has been discovered for previous 64-bit Windows operating systems.[168] Apple provides free updates to the OS for the iPhone through iTunes,and major updates have historically accompanied new models. Such updates often require a newer version of iTunes—for example, the 3.0 update requires iTunes 8.2—but the iTunes system requirements have stayed the same. Updates include bug fixes, security patches and new features.For example, iPhone 3G users initially experienced dropped calls until an update was issued. Version 3.1 required iTunes 9.0, and iOS 4 required iTunes 9.2. iTunes 10.5, which is required to sync and activate iOS 5, requires Mac OS X 10.5.8 or Leopard on G4 or G5 computers on 800 MHz or higher; versions 10.3 and 10.4 and 10.5–10.5.7 are no longer supported. From September 9, 2014, all new iPhone models released were expected to include a new mobile wallet feature developed in conjunction with major credit card issuers American Express, MasterCard, and Visa Support was later added for Discover and UnionPa cards. 

INTERFACE 

The interface is based around the home screen, a graphical list of available applications. iPhone applications normally run one at a time. Starting with the iPhone 4, a primitive version of multitasking came into play. Users could double click the home button to select recently opened applications. However, the apps never ran in the background. Starting with iOS 7, though, apps can truly multitask, and each open application runs in the background when not in use, although most functionality is still available when making a call or listening to music. The home screen can be accessed at any time by a hardware button below the screen, closing the open application in the process. By default, the Home screen contains the following icons: Messages (SMS and MMS messaging), Calendar, Photos, Camera, YouTube, Stocks, Maps (Google Maps), Weather, Voice Memos, Notes, Clock, Calculator, Settings, iTunes (store), App Store, (on the iPhone 3GS and iPhone 4) Compass, FaceTime and GameCenter were added in iOS 4.0 and 4.1 respectively. In iOS 5, Reminders and Newsstand were added, as well as the iPod application split into separate Music and Videos applications. iOS 6 added Passbook as well as an updated version of Maps that relies on data provided by TomTom as well as other sources. iOS 6 also added a Clock application onto the iPad's homescreen. YouTube no longer came as a pre-installed application.
WEB BROWSER  CREATED BY APPLE FOR SECURE BROWSING
Docked at the base of the screen, four icons for Phone, Mail, Safari (Internet), and Music delineate the iPhone's main purposes. On January 15, 2008, Apple released software update 1.1.3, allowing users to create "Web Clips", home screen icons that resemble apps that open a user-defined page in Safari. After the update, iPhone users can rearrange and place icons (by holding down on any icon and moving it to the desired location once they start shaking) on up to nine other adjacent home screens, accessed by a horizontal swipe.Users can also add and delete icons from the dock, which is the same on every home screen. EacH home screen holds up to twenty icons for iPhone 2G, 3G, 4 and 4S, while each home screen for iPhone 5 holds up to twenty-four icons due to a larger screen display, and the dock holds up to four icons. Users can delete Web Clips and third-party applications at any time, and may select only certain applications for transfer from iTunes. Apple's default programs, could only be removed since the iOS 10 update. The 3.0 update adds a system-wide search, known as Spotlight, to the left of the first home screen. Almost all input is given through the touch screen, which understands complex gestures using multi-touch. The iPhone's interaction techniques enable the user to move the content up or down by a touch-drag motion of the finger. For example, zooming in and out of web pages and photos is done by placing two fingers on the screen and spreading them farther apart or bringing them closer together, a gesture known as "pinching". Scrolling through a long list or menu is achieved by sliding a finger over the display from bottom to top, or vice versa to go back. In either case, the list moves as if it is pasted on the outer surface of a wheel, slowly decelerating as if affected by friction. In this way, the interface simulates the physics of a real object. Other user-centered interactive effects include horizontally sliding sub-selection, the vertically sliding keyboard and bookmarks menu, and widgets that turn around to allow settings to be configured on the other side. Menu bars are found at the top and bottom of the screen when necessary. Their options vary by program, but always follow a consistent style motif. In menu hierarchies, a "back" button in the top-left corner of the screen displays the name of the parent folder. 

PHONE 

The iPhone allows audio conferencing,

AUDIO CONFRENCING

call holding, call merging, caller ID, and integration with other cellular network features and iPhone functions. For example, if music is playing when a call is received, the music fades out, and fades back in when the call has ended. The proximity sensor shuts off the screen and touch-sensitive circuitry when the iPhone is brought close to the face, both to save battery and prevent unintentional touches. The iPhone does not support video calling or videoconferencing on versions prior to the fourth generation, as there is only one camera on the opposite side of the screen.The iPhone 4 supports video calling using either the front or back camera over Wi-Fi, a feature Apple calls FaceTime. Voice control, introduced in the iPhone 3GS, allows users to say a contact's name or number and the iPhone will dial it.The first two models only support voice dialing through third-party applications. The iPhone includes a visual voicemail (in some countries)feature allowing users to view a list of current voicemail messages on-screen without having to call into their voicemail. Unlike most other systems, messages can be listened to and deleted in a non-chronological order by choosing any message from an on-screen list. A music ringtone feature was introduced in the United States on September 5, 2007. Users can create custom ringtones from songs purchased from the iTunes Store for a small additional fee. The ringtones can be 3 to 30 seconds long from any part of a song, can fade in and out, pause from half a second to five seconds when looped, or loop continuously. All customizing can be done in iTunes, or with Apple's GarageBand software 4.1.1 or later (available only on Mac OS X) or third-party tools.With the release of iOS 6, which was released on September 19, 2012, Apple added features that enable the user to have options to decline a phone call when a person is calling them. The user can reply with a message, or to set a reminder to call them back at a later time. 


MULTIMEDIA 

The layout of the music library is similar to that of an iPod or current Symbian S60 phones. The iPhone can sort its media library by songs, artists, albums, videos, playlists, genres, composers, podcasts, audiobooks, and compilations. Options are always presented alphabetically, except in playlists, which retain their order from iTunes. The iPhone uses a large font that allows users plenty of room to touch their selection. Users can rotate their device horizontally to landscape mode to access Cover Flow. Like on iTunes, this feature shows the different album covers in a scroll-through photo library. Scrolling is achieved by swiping a finger across the screen. Alternatively, headset controls can be used to pause, play, skip, and repeat tracks. On the iPhone 3GS, the volume can be changed with the included Apple Earphones, and the Voice Control feature can be used to identify a track, play songs in a playlist or by a specific artist, or create a Genius playlist.The iPhone supports gapless playback. Like the fifth-generation iPods introduced in 2005, the iPhone can play digital video, allowing users to watch TV shows and movies in widescreen. Double-tapping switches between widescreen and fullscreen video playback. The iPhone allows users to purchase and download songs from the iTunes Store directly to their iPhone. The feature originally required a Wi-Fi network, but now since 2012, can use the cellular data network if one is not available. The iPhone includes software that allows the user to upload, view, and email photos taken with the camera. The user zooms in and out of photos by sliding two fingers further apart or closer together, much like Safari. The camera application also lets users view the camera roll, the pictures that have been taken with the iPhone's camera. Those pictures are also available in the Photos application, along with any transferred from iPhoto or Aperture on a Mac, or Photoshop on a Windows PC. 


INTERNET CONNECTIVITY 

Internet access is available when the iPhone is connected to a local area Wi-Fi or a wide area GSM or EDGE network, both second-generation (2G) wireless data standards. The iPhone 3G introduced support for third-generation UMTS and HSDPA 3.6, the iPhone 4S introduced support for HSUPA networks (14.4 Mbit/s), and support for HSDPA 7.2 was introduced in the iPhone 3GS .Networks accessible from iPhone models include 1xRTT (represented by a 1x on the status bar) and GPRS (shown as GPRS on the status bar), EDGE (shown as a capital E on the status bar), UMTS and EV-DO (shown as 3G), a faster version of UMTS and 4G (shown as a 4G symbol on the status bar), and LTE (shown as LTE on the status bar).AT&T introduced 3G in July 2004 but as late as 2007, Steve Jobs stated that it was still not widespread enough in the US, and the chipsets not energy efficient enough, to be included in the iPhone Support for 802.1X, an authentication system commonly used by university and corporate Wi-Fi networks, was added in the 2.0 version update. By default, the iPhone will ask to join newly discovered Wi-Fi networks and prompt for the password when required. Alternatively, it can join closed Wi-Fi networks manually. The iPhone will automatically choose the strongest network, connecting to Wi-Fi instead of EDGE when it is available. Similarly, the iPhone 3G and onwards prefer 3G to 2G, and Wi-Fi to either.Wi-Fi, Bluetooth, and 3G (on the iPhone 3G onwards) can all be deactivated individually. Airplane mode disables all wireless connections at once, overriding other preferences. However, once in Airplane mode, one can explicitly enable Wi-Fi and/or Bluetooth modes to join and continue to operate over one or both of those networks while the cellular network transceivers remain off. The iPhone 3GS has a maximum download rate of 7.2 Mbit/s.[199] Furthermore, email attachments as well as apps and media from Apple's various stores must be smaller than 20 MB to be downloaded over a cellular networkLarger files, often email attachments or podcasts, must be downloaded over Wi-Fi (which has no file size limits). If Wi-Fi is unavailable, one workaround is to open the files directly in Safari.Safari is the iPhone's native web browser, and it displays pages similar to its Mac and Windows counterparts. Web pages may be viewed in portrait or landscape mode and the device supports automatic zooming by pinching together or spreading apart fingertips on the screen, or by double-tapping text or images.Safari does not allow file downloads except for predefined extensions. The iPhone does not support Flash. Consequently, the UK's Advertising Standards Authority adjudicated that an advertisement claiming the iPhone could access "all parts of the internet" should be withdrawn in its current form, on grounds of false advertising.

INTERNET CONNECTIVITY OF IPHONE

In a rare public letter in April 2010, Apple CEO Steve Jobs outlined the reasoning behind the absence of Flash on the iPhone (and iPad). The iPhone supports SVG, CSS, HTML Canvas, and Bonjour. Google Chrome was introduced to the iOS on June 26, 2012. In a review by Chitika on July 18, 2012, they announced that the Google Chrome web browser has 1.5% of the iOS web browser market since its release.The Maps application can access Google Maps in map, satellite, or hybrid form. It can also generate directions between two locations, while providing optional real-time traffic information. During the iPhone's announcement, Jobs demonstrated this feature by searching for nearby Starbucks locations and then placing a prank call to one with a single tap.Support for walking directions, public transit, and street view was added in the version 2.2 software update, but no voice-guided navigation.The iPhone 3GS and iPhone 4 can orient the map with its digital compass.Apple also developed a separate application to view YouTube videos on the iPhone, which streams videos after encoding them using the H.264 codec. Simple weather and stock quotes applications also tap into the Internet. IPhone users can and do access the Internet frequently, and in a variety of places. According to Google, in 2008, the iPhone generated 50 times more search requests than any other mobile handset. According to Deutsche Telekom CEO René Obermann, "The average Internet usage for an iPhone customer is more than 100 megabytes. This is 30 times the use for our average contract-based consumer customers." Nielsen found that 98% of iPhone users use data services, and 88% use the internet.[ In China, the iPhone 3G and iPhone 3GS were built and distributed without Wi-Fi. With the introduction of the Verizon iPhone in January 2011, the issue of using internet while on the phone was brought to the public's attention. Under the two US carriers, internet and phone could be used simultaneously on AT&T networks, whereas Verizon networks only support the use of each separately. However, in 2014, Verizon announced that the iPhone 6 and 6 Plus would allow simultaneous voice and data over its LTE Network.[citation needed] T-Mobile and Sprint have enabled calls over Wi-Fi, with Verizon and AT&T soon doing the same.


TEXT 

For text input, the iPhone implements a virtual keyboard on the touchscreen. It has automatic spell checking and correction, predictive word capabilities, and a dynamic dictionary that learns new words. The keyboard can predict what word the user is typing and complete it, and correct for the accidental pressing of keys near the presumed desired key. The keys are somewhat larger and spaced farther apart when in landscape mode, which is supported by only a limited number of applications. Touching a section of text for a brief time brings up a magnifying glass, allowing users to place the cursor in the middle of existing text. The virtual keyboard can accommodate 21 languages, including character recognition for Chinese. Alternate characters with accents (for example, letters from the alphabets of other languages) and emoji can be typed from the keyboard by pressing the letter for 2 seconds and selecting the alternate character from the popup. The 3.0 update brought support for cut, copy, or pasting text, as well as landscape keyboards in more applications. On iPhone 4S and above, Siri allows dictation. 


E-MAIL AND TEXT MESSAGES 

The iPhone also features an email program that supports HTML email,

E-MAIL ON IPHONE

which enables the user to embed photos in an email message. PDF, Word, Excel, and PowerPoint attachments to mail messages can be viewed on the phone. Apple's MobileMe platform offers push email, which emulates the functionality of the popular BlackBerry email solution, for an annual subscription. Yahoo! offers a free push-email service for the iPhone. IMAP (although not Push-IMAP) and POP3 mail standards are also supported, including Microsoft Exchange and Kerio ConnecTED In the first versions of the iPhone firmware, this was accomplished by opening up IMAP on the Exchange server. Apple has also licensed Microsoft ActiveSync and supports the platform (including push email) with the release of iPhone 2.0 firmware.The iPhone will sync email account settings over from Apple's own Mail application, Microsoft Outlook, and Microsoft Entourage, or it can be manually configured on the device itself. The email program can access almost any IMAP or POP3 account Text messages are presented chronologically in a mailbox format similar to Mail, which places all text from recipients together with replies. Text messages are displayed in speech bubbles (similar to iChat) under each recipient's name. The iPhone has built-in support for email message forwarding, drafts, and direct internal camera-to-email picture sending. Support for multi-recipient SMS was added in the 1.1.3 software update. Support for MMS was added in the 3.0 update, but not for the original first generation iPhone and not in the US until September 25, 2009. 


THIRD PARTY APPLICATIONS 

At WWDC 2007 on June 11, 2007, Apple announced that the iPhone would support third-party web applications using Ajax that share the look and feel of the iPhone interface.On October 17, 2007, Steve Jobs, in an open letter posted to Apple's "Hot News" weblog, announced that a software development kit (SDK) would be made available to third-party developers in February 2008. The iPhone SDK was officially announced and released on March 6, 2008, at the Apple Town Hall facility. It is a free download, with an Apple registration, that allows developers to develop native applications for the iPhone and iPod Touch, then test them in an "iPhone simulator". However, loading an application onto a real device is only possible after paying an Apple Developer Connection membership fee. Developers are free to set any price for their applications to be distributed through the App Store, of which they will receive a 70% share.Developers can also opt to release the application for free and will not pay any costs to release or distribute the application beyond the membership fee. The App Store was launched with the release of iOS 2.0, on July 11, 2008.The update was free for iPhone users; owners of older iPod Touches were required to pay US$10 for it. Once a developer has submitted an application to the App Store, Apple holds firm control over its distribution. Apple can halt the distribution of applications it deems inappropriate, for example, I Am Rich, a US$1000 program that simply demonstrated the wealth of its user. Apple has been criticized for banning third-party applications that enable a functionality that Apple does not want the iPhone to have: In 2008, Apple rejected Podcaster, which allowed iPhone users to download podcasts directly to the iPhone claiming it duplicated the functionality of iTunes.Apple has since released a software update that grants this capability.NetShare, another rejected app, would have enabled users to tether their iPhone to a laptop or desktop, using its cellular network to load data for the computer. Many carriers of the iPhone later globally allowed tethering before Apple officially supported it with the upgrade to the iOS 3.0, with AT&T Mobility being a relative latecomer in the United States.were permitted to design "Web Apps" that would run through Safari.Unsigned native applications are also available for "jailbroken" phones. The ability to install native applications onto the iPhone outside of the App Store is not supported by Apple, the stated reason being that such native applications could be broken by any software update, but Apple has stated it will not design software updates specifically to break native applications other than those that perform SIM unlocking.As of October 2013, Apple has passed 60 billion app downloads. As of September 2016, there have been over a 140 billion apps downloaded from the App Store.
