*** Please help me***.. I have an ipad2 Wi-Fi + 3G and initially the 3G service worked perfectly. Yesterday I noticed that when I went into settings and clicked on Cellular Data I didn't have the option to view my account anymore and in the carrier space where AT&T goes it said unavailable. After that I tried to log on to Safari but all I received was an error stating "the server had timed out." I was going to restore it on my iMac but when I hooked it up to be restored I received an error that stated "iPad Update Server is unavailable." I then tried to restore it on a PC but I received the same error. If any has any ideas on how to solve this problem I would be eternally grateful...
