Hi,
I restored to the iOS 5 GM and I also have a registered UDID so I thought this will go fine but then it asked for my official carrier sim which I don't have so I looked for a method to hacktivate it and I found sn0wbreeze. After doing the advanced mode thing, it all went well, iTunes finished its job and then the iPhone rebooted and the Apple logo came back on stuck with the loading bar empty. I restored back to 4.3.3 but I would love to be able to install the new iOS.
