For some reason, iTunes will not downgrade my iPad from 5 Beta 4 to 4.3.3 or anything lower. I get the famous "This device isn't eligible for the requested build." error message. I've Google'd this problem for over an hour and I can't find anything. I've made sure my hosts file doesn't have the "gs.apple.com" entry in it, so that's not the problem. I've tried multiple .ipws restore files and I get the same thing. I tried an "Erase and Reset" option, still nothing. Anybody know of anything else I can try?
