Apple iPhones
 

The iPhone is an Internet-enabled multimedia mobile phone designed and marketed by Apple Inc. It has a multi-touch screen with virtual keyboard and buttons, but a minimal amount of hardware input. The iPhone's functions include those of a camera phone and portable media player (iPod) in addition to text messaging and visual voicemail. It also offers Internet services including e-mail, web browsing, and local Wi-Fi connectivity. The first generation phone hardware was quad-band GSM with EDGE; the second generation uses UMTS and HSDPA. Apple announced the iPhone on 9 January 2007. The announcement was preceded by rumors and speculations that circulated for several months. The iPhone was initially introduced in the United States on 29 June 2007 and is in the process of being introduced worldwide. It was named Time magazine's Invention of the Year in 2007. On 9 June 2008, the iPhone 3G was unveiled, which supports 3G phone standard and includes Assisted GPS.

The iPhone allows audio conferencing, call holding, call merging, caller ID, and integration with other cellular network features and iPhone functions. For example, a playing song fades out when the user receives a call. Once the call is ended the music fades back in. Voice dialing and video calling are not supported by the iPhone. The iPhone includes a visual voicemail 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. AT&T, O2, T-Mobile Germany, and Orange modified their voicemail infrastructure to accommodate this new feature designed by Apple. A lawsuit has been filed against Apple and AT&T by Klausner Technologies claiming the iPhone's visual voicemail feature infringes two patents. A music ringtone feature was introduced in the United States on September 5, 2007, but is not yet available in all countries where the iPhone has been released. This feature allows users to create custom ringtones from their purchased iTunes music library for an additional fee equal to the price of a song. The ringtones can be from 3 to 30 seconds in length of any part of a song, can include fading in and out, can pause from half a second to five seconds when looped, and never expire. All customizing can be done in iTunes, and the synced ringtones can also be used for alarms on the iPhone. Custom ringtones can also be created using Apple's GarageBand software 4.1.1 or later (available only on Mac OS X) and third-party tools.

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. The YouTube application streams videos over Wi-Fi, 2G, or 3G after encoding them using QuickTime's 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. At WWDC 2007 on June 11, 2007 Apple announced that the iPhone will 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 will also allow application development for the iPod touch. The iPhone SDK was officially announced on March 6, 2008, at the Apple Town Hall facility.[53] 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 US$99 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. Developers can also opt to release the application for free and will not pay any costs to release or distribute the application beyond the US$99 membership fee. The SDK is available immediately, while the launch of applications will require waiting until a firmware update in early July 2008. This update will be free for iPhone users, however, there will be a charge for iPod touch owners. Many third party Safari "applications" and un-signed native applications are also available. 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.
