ok, so like an idiot I installed beta 4. I don't have a developer license but I do work on iphone apps. Thus, I have provisioning files installed on my ipad 3. Problem is, after *upgrading* to iOS 6 beta, I can't sign in with my apple id. Now, I can't install any of my apps becuase it won't let me sign into the app store. Oddly, icloud works. Clearly, this was a mistake. Is there a solution or, do I have to roll back to iOS 5? Any help would be greatly appreciated.
