I stupidly tried to get the new ios 7 beta 2 on my iPad today without a UDID or dev account and it is now showing Activation Error, saying I have to log in to the developer website and add it to my developer account (it says the same thing in iTunes and shows no other info or options). Well I don't have one. All I want to do is restore my iPad to the newest ios 6 version and have a working ipad again. I don't care if I lose my data, I just need to fix this. Please help!
