At the Macworld Conference & Expo in January 2007, Steve Jobs revealed the long anticipated iPhone, a convergence of an Internet-enabled smartphone and iPod.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").The iPhone first became available on June 29, 2007 for $499 (4 GB) and $599 (8 GB) with an AT&T contract.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.On June 9, 2008, at WWDC 2008, Steve Jobs announced that the iPhone 3G would be available on July 11, 2008.This version added support for 3G networking, assisted-GPS navigation, and a price cut to $199 for the 8 GB version, and $299 for the 16 GB version, which was available in both black and white. The new version was visually different from its predecessor in that it eliminated the flat silver back, and large antenna square for a curved glossy black or white back. Following complaints from many people, the headphone jack was changed from a recessed jack to a flush jack to be compatible with more styles of headphones. The software capabilities changed as well, with the release of the new iPhone came the release of Apple's App Store; the store provided applications for download that were compatible with the iPhone. On April 24, 2009, the App Store surpassed one billion downloads.On June 8, 2009, at Apple's annual worldwide developers conference, the iPhone 3GS was announced, providing an incremental update to the device including faster internal components, support for faster 3G speeds, video recording capability, and voice control. On June 7, 2010, at WWDC 2010, the iPhone 4 was announced, which Apple says is its "'biggest leap we've taken" since the original iPhone.The phone includes an all-new design, 960x640 display, Apple's A4 processor used in the iPad, a gyroscope for enhanced gaming, 5MP camera with LED flash, front-facing VGA camera and FaceTime video calling. Shortly after the release of the iPhone 4, it was realized by consumers that the new iPhone had reception issues. This is due to the stainless steel band around the edge of the device, which also serves as the phones cellular signal and Wi-Fi antenna. The current fix for this issue is a "Bumper Case" for the phone distributed for free to all iPhone 4 owners, subject to terms.
