With the announcement of an October 12 ship date for iOS 5, Apple today posted the Golden Master (GM) release of iOS 5 to developers this afternoon, 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" and encourages 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."

Back up, restore, then restore from back up. Good to go.
Agreed, can't wait to have this on my iPhone 4.
Check your hosts file. Probably messed up due to TinyUmbrella.
