At the iPhone 5 launch event in San Francisco today, Apple confirmed that iOS 6 will launch on September 19th. The upgrade will, of course, be compatible with the new iPhone 5, as well as the iPhone 4S, iPhone 4, iPhone 3GS, iPad 2, and the new iPad. The upgrade will be free.
Apple did not show off any new features for iOS 6 other than what was already detailed at its WWDC unveiling in June. They did state that iOS 6 has been designed from the beginning to take advantage of the iPhone 5’s new 4″ 1136×640 display. All of Apple’s built-in apps have been updated to make use of the larger display.
