The iOS 7 golden master update can be obtained through Apple's online developer portal. People familiar with the software said it is identified as "Build 11A465."
The release of the iOS 7 GM means that developers will have a little over a week to test their applications before the software is made available to the masses. Apple announced earlier Tuesday that iOS 7 will be made available to the public on Wednesday, Sept. 18.
iOS 7 will launch just two days before Apple's latest smartphones ? the iPhone 5s and iPhone 5c ? go on sale. Both of those devices will ship with iOS 7 preinstalled.
For current iOS device users, iOS 7 will become available for iPhone 5, iPhone 4S, and iPhone 4; the fourth- and third-generation iPad, iPad 2, and iPad mini, as well as the fifth-generation iPod touch. It will be a free download.
