Introducing  iPhone 3G. With fast 3G wireless technology, GPS mapping, support for enterprise features like Microsoft Exchange, and the new App Store, iPhone 3G puts even more features at your fingertips. And like the original iPhone, it combines three products in one — a revolutionary phone, a widescreen iPod, and a breakthrough Internet device with rich HTML email and a desktop-class web browser. iPhone 3G. It redefines what a mobile phone can do — again

Apple iPhone is an internet connected multimedia smartphone with a flush multi-touch screen and a minimal hardware interface. Lacking a physical keyboard, a virtual keyboard is rendered on the touch screen. 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 also adds UMTS with HSDPA.

Apple announced the iPhone on January 9, 2007.The announcement was preceded by rumors and speculation that circulated for several months. The iPhone was initially introduced in the United States on June 29, 2007 and is in the process of being introduced worldwide. It was named Time magazine's Invention of the Year in 2007. On July 11, 2008, the iPhone 3G was released and supported faster 3G data speeds and Assisted GPS.
