I desperately need help asap. I just restored my ipad 2 to stock as I'm about to sell it, but now it won't activate. The last error message I received was a -50 error. (I searched and couldn't find anything on this error). Now as soon as my ipad is connected to itunes I get a message. "There is a problem with your iPad. We're sorry, the iPad you connected may be damaged and cannot be activated for service. We recommend you visit your nearest Apple Store for more information." I tried calling my closest apple store, which is an hour and a half from me but could not get a live person on the phone. I purchased my ipad 2 back in June if it matters.
