iPhone
From the iPhone Games Wiki, a database for iPhone/iPod Touch games that anyone can edit
The iPhone is an internet-connected multimedia smartphone designed and marketed by Apple Inc. with a flush multi-touch screen and a minimal hardware interface. The device does not have a physical keyboard, so a virtual keyboard is rendered on the touch screen instead. The iPhone functions as a camera phone (including text messaging and visual voicemail), a portable media player (equivalent to an iPod), and an Internet client (with email, web browsing, and local Wi-Fi connectivity).
The iPhone was initially introduced in the United States on June 29, 2007 and has since been introduced worldwide. It was named Time magazine's "Invention of the Year" in 2007. On July 11, 2008, the iPhone 3G was released. It supports faster 3G data speeds and Assisted GPS.

[edit] History
Development of iPhone began with Apple CEO Steve Jobs' direction that Apple engineers investigate touchscreens. Apple created the device during a secretive and unprecedented collaboration with AT&T Mobility—Cingular Wireless at the time at a 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-house. Numerous codenames and even fake prototypes were devised to keep the project secret.
Jobs unveiled iPhone to the public on January 9, 2007 in a keynote address. Apple was required to file for operating permits with the FCC, but such filings are available to the public, so the announcement came several months before the iPhone received approval. The iPhone went on sale in the United States on June 29, 2007. Apple closed its stores at 2:00 pm local time to prepare for the 6:00 pm iPhone launch, while hundreds of customers lined up at stores nationwide.
[edit] Hardware
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 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. Most gloves or a stylus prevent the necessary electrical conductivity. The screen is also capable of rendering up to 262,144 colors.
Loudspeakers are located above the screen and the left side of the bottom of the unit; the microphone is located on the right. Volume controls are located on the left side of the unit and as a slider in the iPod application. Both speakers are used for handsfree operations and media playback.
The iPhone features an internal rechargeable battery. It is not user-replaceable, similar to the batteries of existing iPods, and unlike those of most existing cellular phones. 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 is extended to two years with AppleCare.
The SIM card is located in a slot at the top of the device. It can be ejected with a paperclip or a tool included with the iPhone 3G. In most countries, the iPhone is usually sold with a SIM lock, which prevents the iPhone from being used on different mobile networks.
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. All data is stored on an internal flash drive; the iPhone does not contain any memory card slots for expanded storage.
[edit] Software
iPhone OS is the operating system running on the iPhone (both original and 3G models) and the 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 interface's smooth animations. The operating system takes up less than half a GB of the device's total 8 GB or 16 GB storage. It is capable of supporting bundled and future applications from Apple, as well as from third-party developers. Software applications cannot be copied from Mac OS X but must be written and compiled specifically for the iPhone.
Like the 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 or 64-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. Apple provides free updates to the iPhone's operating system through iTunes, in a similar fashion to the way that iPods are updated. Security patches, as well as new and improved features, are released in this fashion.
The interface is based around the home screen, a graphical list of available applications. iPhone apps normally run one at a time, 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: Text (SMS messaging), Calendar, Photos, Camera, YouTube, Stocks, Maps (Google Maps), Weather, Clock, Calculator, Notes, Settings, iTunes (store), and App Store. Docked at the base of the screen, four icons for Phone, Mail, Safari (Internet), and iPod (music) delineate the iPhone's main purposes.
The iPhone allows audio conferencing, call holding, call merging, caller ID, and integration with other cellular network features and iPhone functions. For example, if a song is playing while a call is received, it gradually fades out, and fades back 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 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 to touch their selection. Users can rotate their device horizontally to access Cover Flow. Like on iTunes, it shows the different album covers in a scroll-through photo library. Scrolling is achieved by swiping a finger across the screen.
