When it prompts you to log in, it will pull up your appleID for you, but it gets it wrong. It will pull up some random other appleID...sometimes an old one you created for iTunes using a hotmail account you haven't checked since 2004, but sometimes a completely random other person's appleID. The authentication is unpredictable too...my wife has successfully signed on to her current account using an old password and successfully signed on to an old account using her new accounts password. Most of the time she can't sign on at all.
