The layout of the music library is similar to iPods and current Symbian S60 phones, with the sections divided more clearly alphabetically, and with a larger font. Just like iPods, the iPhone can sort its media library by songs, artists, albums, videos, playlists, genres, composers, podcasts, audiobooks, and compilations. Cover Flow, like that on iTunes, shows the different album covers in a scroll-through photo library. Scrolling is achieved by swiping a finger across the screen.

The iPhone supports gapless playback.^[53]

Like the fifth generation iPods introduced in 2005, the iPhone can play video, allowing users to watch TV shows and films. Unlike other image-related content, video on the iPhone plays only in the landscape orientation, when the phone is turned sideways. Double tapping switches between wide-screen and full-screen video playback.

The iPhone allows users to purchase and download songs from the iTunes Store directly to their iPhone over Wi-Fi with the iTunes Wi-Fi Music Store, but not over the cellular data network.^[54]

iPhone OS is the operating system that runs on the iPhone and iPod touch. It is based on a variant of the same basic Mach kernel that is found in Mac OS X. iPhone OS includes the software component “Core Animation” from Mac OS X v10.5 which, together with the PowerVR MBX 3D hardware, is responsible for the smooth animations used in its user interface. The operating system takes up considerably less than half a GB of the device’s total 8 GB or 16 GB storage.^[37] It is capable of supporting bundled and future applications from Apple, as well as applications written by third-party developers and published through the iTunes Store.

Like an iPod, the iPhone is managed with iTunes version 7.3 or later, which is compatible with Mac OS X version 10.4.10 or later, and 32-bit Windows XP or Vista.^[38] The release of iTunes 7.6 expanded this support to include 64-bit versions of XP and Vista,^[39] and a workaround has been discovered for previous 64-bit Windows operating systems.^[40]

The iPhone’s applications cannot simply be copied from Mac OS X and have to be written and compiled specifically for the iPhone. Additionally, the Safari web browser supports web applications written with A

Sim Slot

Applications

There are several applications located on the Home screen: Text (SMS messaging), Calendar, Photos, Camera, YouTube, Stocks, Maps (Google Maps), Weather, Clock, Calculator, Notes, Settings, and iTunes (store). Four other applications, docked at the base of the screen, delineate the iPhone’s main purposes: Phone, Mail, Safari, and iPod.[41]

The YouTube application streams videos over Wi-Fi, 2G, or 3G after encoding them using the open H.264 codec, to which YouTube has converted about 10,000 videos. As a result, the YouTube application on iPhone can currently view only a certain selection of videos from the site.[42]

At WWDC 2007 on June 11, 2007 Apple announced that the iPhone would support third-party “applications” via the Safari web browser 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. Due to security concerns and Jobs’ praise of Nokia’s digital signature system, it was suggested that Apple would adopt a similar method. The SDK has also allowed application development for the iPod touch.[43] The iPhone SDK was officially announced on March 6, 2008, at the Apple Town Hall facility.[44] The SDK will allow developers to develop native applications for the iPhone and iPod touch, as well as test them in an “iPhone simulator”. However, loading an application onto the devices is only possible after paying a 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 percent share[45]. 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 SDK was made available immediately, while the launch of applications had to wait until the firmware update which was released on July 11, 2008.[46] This update is free for iPhone users and there is a charge for iPod touch owners.

Once a developer has submitted his/her application to the App Store, Apple holds firm control over its distribution. For example, Apple can halt the distribution of applications it deems inappropriate as has happened with a $1000 program that has as sole purpose to demostrate the wealth of its user.[47] More strikingly, Apple also installs a kill switch in the programs it distributes through the App store: all applications can be remotely disabled at Apple’s command. The company considers it irresponsible not to have this kind of control over the software the user runs[47].

Many third-party Safari “applications” and un-signed native applications are also available.[48] The ability to install native applications onto the iPhone outside of the App Store will not be supported by Apple. 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 applications that perform SIM unlocking.[49] As of September 15, 2008, iPhone software version 2.1 is still “exploitable” by the same method that enabled unsigned applications in software versions as early as version 1.1.3, indicating that Apple is making good on their promise not to intentionally cripple unofficial development.

The 9 cm (3.5 in) liquid crystal display (320×480 px at 6.3 px/mm, 160 ppi) HVGA touchscreen with scratch-resistant glass[15] is specifically created for use with a finger, or multiple fingers for multi-touch sensing. Because the screen is a capacitive touchscreen, bare skin is required; a stylus or a normal glove prevents the necessary electrical conductivity.[16][17][18][19]

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 itself 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. Similarly, scrolling through a long list in a menu works as if the list is pasted on the outer surface of a wheel: the wheel can be “spun” by sliding a finger over the display from bottom to top (or vice versa). In either case, the list continues to move based on the flicking motion of the finger, slowly decelerating as if affected by friction. In this way, the interface simulates the physics of a real 3D object. There are other visual effects, such as horizontally sliding sub-selections and co-selections from right and left, vertically sliding system menus from the bottom (e.g. favorites, keyboard), and menus and widgets that turn around to allow settings to be configured on their back sides.

The display responds to three sensors. A proximity sensor shuts off the display and touchscreen when the iPhone is brought near the face to save battery power and to prevent inadvertent inputs from the user’s face and ears. An ambient light sensor adjusts the display brightness which in turn saves battery power. A 3-axis accelerometer senses the orientation of the phone and changes the screen accordingly.[20] Photo browsing, web browsing, and music playing support both upright and left or right widescreen orientations, while videos play in only one widescreen orientation, with the home button to the left.[21]

A software update allowed the first generation iPhone to use cell towers and Wi-Fi networks to locate itself despite lacking a hardware GPS. The iPhone 3G includes A-GPS but also uses cell towers and Wi-Fi for location finding.

A single “home” hardware button below the display brings up the main menu. Subselections are made via the touchscreen. The iPhone utilizes a full-paged display, with context-specific submenus at the top and/or bottom of each page, sometimes depending on screen orientation. Detail pages display the equivalent of a “Back” button to return to the parent menu.

The iPhone has three physical switches on its sides: wake/sleep, volume up/down, and ringer on/off. These are made of plastic on the original iPhone and metal on the iPhone 3G. All other multimedia and phone operations are done via the touchscreen. The iPhone 3G features a full plastic back to increase GSM signal strength.[22] It also comes in white exclusively for the 16GB model.

Audio

The iPhone’s headphones are similar to those of most current smartphones, incorporating a microphone. A multipurpose button in the microphone can be used to play or pause music, skip tracks, and answer or end phone calls without touching the iPhone. The 3.5 mm TRS connector for the headphones is located on the top left corner. The headphone socket on the original iPhone is recessed into the casing. The recess is narrow when compared to many headphone jacks, making them incompatible without the use of an adapter.[23] The iPhone 3G has a flush mounted headphone socket.

Wireless earpieces that use Bluetooth technology to communicate with the iPhone are sold separately. It does not support stereo audio.

The loudspeaker is used both for handsfree operations and media playback, but does not support voice recording.

Composite or component video at up to 576i and stereo audio can be output from the dock connector using an adapter sold by Apple.[24]

Battery

The iPhone features a built-in rechargeable battery that is not user-replaceable, similar to existing iPods, but dissimilar to most existing cellular phones.[25][26] If the battery prematurely reaches the end of its life, the phone can be returned to Apple and replaced for free while still in warranty,[27] one year at purchase and extended to two years with AppleCare. The cost of having Apple provide a new battery and replace it when the iPhone is out of warranty is, in the United States, US$79 and US$6.95 for shipping.[28]

Since July 2007 third party battery packs have been available[29] 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 original iPhone has been soldered in. Therefore a soldering iron is required to install the new battery. This is not the case with the iPhone 3G as it uses a different battery fitted with a connector.[30]

The original iPhone’s battery was stated to be capable of providing up to seven hours of video, six hours of web browsing, eight hours of talk time, 24 hours of music or up to 250 hours on standby.[15] Apple’s site says that the battery life “is designed to retain up to 80% of its original capacity after 400 full charge and discharge cycles”,[31] which is comparable to the iPod batteries.

The iPhone 3G’s battery is stated to be capable of providing up to seven hours of video, six hours of web browsing on Wi-Fi or five on 3G, ten hours of 2G talk time, or five on 3G, 24 hours of music, or 300 hours of standby.[9]

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.[32] Though the battery replacement service and its pricing was not made known to buyers until the day the product was launched,[32][33] a similar service had been well established for the iPods by Apple and various third party service providers.

Storage

The iPhone was initially released with two options for internal storage size; either a 4 GB or 8 GB flash drive (manufactured by Samsung) model was available. On September 5, 2007, Apple announced they were discontinuing the 4 GB models.[35] On February 5, 2008, Apple announced the addition of a 16 GB model to the iPhone lineup.[36] The iPhone does not contain any memory card slots for expanded storage.
