At the Macworld Conference & Expo in January 2007, Steve Jobs revealed the long anticipated[132] iPhone, a convergence of an Internet-enabled smartphone and iPod.[133] The original iPhone combined a 2.5G quad band GSM and EDGE cellular phone with features found in hand held devices, running scaled-down versions of Apple's Mac OS X (dubbed iOS, formerly iPhone OS), with various Mac OS X applications such as Safari and Mail. It also includes web-based and Dashboard apps such as Google Maps and Weather. The iPhone features a 3.5-inch (89 mm) touch screen display, 4, 8, or 16 GB of memory, Bluetooth, and Wi-Fi (both "b" and "g").[133] The iPhone first became available on June 29, 2007 for $499 (4 GB) and $599 (8 GB) with an AT&T contract.[134] On February 5, 2008, Apple updated the original iPhone to have 16 GB of memory, in addition to the 8 GB and 4 GB models.
