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; 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.
Apple announced the iPhone on Jan. 9, 2007 (5 years ago), after months of rumors and speculation. The original iPhone was introduced in the United States on Jun. 29, 2007 (5 years ago) before being marketed worldwide. Time magazine named it the Invention of the Year in 2007 (5 years ago).
