History of iPad 4

Manufacture

The iPad is assembled by Foxconn, which also manufactures Apple's iPod, iPhone and Mac Mini, in its largest plant in Shenzhen, China.[46]

iSuppli estimated that each iPad 16 GB Wi-Fi version costs $259.60 to manufacture, a total that excludes research, development, licensing and patent costs.[47] Apple does not disclose the makers of iPad components, but teardown reports and analysis from industry insiders indicate that various parts and their suppliers include:

    * Apple A4 SoC: Samsung.[9][48]
    * NAND flash RAM chips: Toshiba; except Samsung for the 64 GB model.[49][50]
    * Touch-screen chips: Broadcom.[49]
    * IPS Display: LG Display
    * Touch panels: Wintek. (Got the job after TPK Touch Solutions was unable to fulfill its orders, delaying the iPad's release from late March to early April.[51])

    * Case: Catcher Technologies.[52]
    * LCD drivers: Novatek Microelectronics.[53]
    * Batteries: 60% are made in Taiwan by Simplo Technology, 40% by Dynapack International.[35][54]
    * Accelerometer: STMicroelectronics.[55]

Software

Like the iPhone, with which it shares a development environment (iPhone SDK, or software development kit, version 3.2 onwards),[56] the iPad only runs its own software, software downloaded from Apple's App Store, and software written by developers who have paid for a developer's license on registered devices.[57] The iPad runs almost all third-party iPhone applications, displaying them at iPhone size or enlarging them to fill the iPad's screen.[58] Developers may also create or modify apps to take advantage of the iPad's features.[59] Application developers use iPhone SDK for developing applications for iPad.[60] The iPad has been shipping with a customized iPad-only version of iPhone OS, dubbed v3.2. On September 1, it was announced the iPad would get iOS 4.2 by November 2010.[61] Apple released iOS 4.2.1 to the public on November 22.[62]

Applications

The iPad comes with several applications, including Safari, Mail, Photos, Video, YouTube, iPod, iTunes, App Store, iBooks, Maps, Notes, Calendar, Contacts, and Spotlight Search.[63] Several are improved versions of applications developed for the iPhone.

The iPad syncs with iTunes on a Mac or Windows PC.[19] Apple ported its iWork suite from the Mac to the iPad, and sells pared down versions of Pages, Numbers, and Keynote apps in the App Store.[64] Although the iPad is not designed to replace a mobile phone, a user can use a wired headset or the built-in speaker and microphone and place phone calls over Wi-Fi or 3G using a VoIP application.[65] The iPad has lots of third party applications available for it; as of September 1, 2010, there were 25,000 iPad specific apps on the App Store.[66] The iPad cannot run Xcode since it use the iOS.[67]
