Apple has seeded the Golden Master (GM) version of iOS 7 to developers. This represents the final build that will be released to the public on September 18 for installation on existing devices.
The GM version of iOS 7 arrives as build 11A465, and Apple has also released a GM build of Xcode 5 to support iOS 7. However, the iOS 7 GM is compatible with the iPhone 5, iPhone 4S, iPhone 4, iPad (third and fourth generations), iPad mini and iPod touch (fourth and fifth generations) models.
iOS 7 GM will be the last non-public iOS build Apple releases before iOS 7 is made available to the public next week. The OS download files are now available at Apple’s dev center.
