You'll need some things: An supported iDevice IOS 5.1.1 or 5.1 IOS 6 beta 1 (Go see a friend who has it) iTunes 10.6.3 So first thing you need to do is a freshrestore to 5.1.1 or 5.1, it wouldn't be wise to use a jailbroken device. Then complete the setup until you are on your homescreen. Then just update (restoring your device WILL NOT work!) (edit: press shift key+update on windows or option key+update on mac) EDIT: I've tested in on all BETA firmwares, works on every singe one of them. That's the only thing. It works without UDID. Have fun with IOS 6.
