IPhone

The iPhone is an Internet and multimedia enabled smartphone designed and marketed by Apple Inc. Because its minimal hardware interface lacks a physical keyboard, the multi-touch screen renders a virtual keyboard when necessary. The iPhone functions as a camera phone (also including text messaging and visual voicemail), a portable media player (equivalent to a video iPod), and an Internet client (with email, web browsing, and Wi-Fi connectivity). The first-generation phone hardware was quad-band GSM with EDGE; the second generation added UMTS with 3.6 Mbps HSDPA;[17] the third generation adds support for 7.2 Mbps HSDPA downloading but remains limited to 384 Kbps uploading as Apple had not implemented the HSPA protocol.[18]
Apple announced the iPhone on January 9, 2007,[19] after months of rumors and speculation.[20] The original iPhone was introduced in the United States on June 29, 2007 before being marketed worldwide. Time magazine named it the Invention of the Year in 2007.[21] Released July 11, 2008, the iPhone 3G supports faster 3G data speeds and assisted GPS.[17] On March 17, 2009, Apple announced version 3.0 of the iPhone OS operating system for the iPhone (and iPod Touch), released on June 17, 2009.[22] The iPhone 3GS was announced on June 8, 2009, and has improved performance, a camera with more megapixels and video capability, and voice control.[23] It was released in the U.S., Canada and 6 European countries on June 19, 2009,[3] in Australia and Japan on June 26,[24] and saw international release in July and August, 2009.
