About 2 months ago my sister purchased an iPad 2 from Best Buy. First, she wanted a 3G version and, without her consent, the clerk ran a credit check as if she were getting a cell phone. When I she told me about it I told her that wasn't right and that the advantage of the 3G service was that there is no contract and generally prepaid, therefore no need for a credit check. We contacted both Apple and Verizon and both responded that it was not required. She promptly returned it and bought one from Verizon. As this was her first iPad, and Apple product generally, she did not restore before taking it back. Last night, I started getting strange messages from her iMessage account. I knew it wasn't her, but I assumed that it was her husband playing a joke on me. This morning she called to tell me that it was neither her or her husband. About an hour later I started getting messages about a cautionary tale that Best Buy failed to restore and I was getting these messages from the person that subsequently purchased the iPad that she returned. They assured me that they would be clearing the iPad, but you can never be sure. Has this ever happened to anyone else? Also, are there any other steps that she should be taking to ensure that her account is no longer connected to the old iPad? Sorry for the long post, thanks in advance.
