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 (equivalent to the 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.[29]
Apple announced the iPhone on 9 January 2007.[30] The announcement was preceded by rumors and speculations that circulated for several months.[31] 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.[32] On 11 July 2008, the iPhone 3G was released and supported faster 3G data speeds and Assisted GPS,[29] though many units worldwide initially failed to activate because Apple's iTunes servers were overloaded.
