Yesterday Apple announced that iOS 5 would get an October 12 release date. 5. Today Apple already posted the Golden Master (GM) release of iOS 5 to developers, with a build number of 9A334.
Apple notes that users
“must use iTunes 10.5 beta 7 to install iOS 5 GM seed on your devices. iOS 5 GM seed is not available via over the air software update”
Furthermore they encourage users to back up their devices via iCloud before installing the GM.
Apple posted a GM seed of Xcode 4.2 as well, and notes that:
The GM seed “can now be used to submit iOS 5 applications to the App Store for review.”
Since the GM doesn’t require a developer account this release is available for everyone to use, due to copyright infringements we can’t post the downloads here, but there are several sites which provide how to guides as well as the files needed.
