Just purchased a "new", locked to AT&T 3gs off of ebay. Cannot for the life of me get it activated. During the activation process it displays "Your current number is ###-###-#### but it is not my phone number. Then when I enter my billing zip code and last 4 of my social it displays that AT&T cannot verify the information entered. I just spent two hours on the phone with AT&T and Apple - AT&T linked the IMEI of the phone to my SIM # and Apple instructed a reboot and restore to factory settings. Did that and it's still coming up with the phone number that doesn't belong to me (it's a Michigan # and the seller is located in Michigan). At this point I've been advised to just return the phone. Do I have any other options? Should I bother setting up an appointment at the Genius Bar or don't waste my time? Any help or suggestions would be appreciated. Thank you.
