I got a new iPhone 3GS from craiglist and it was AT&T locked. So i did the unlock for this phone through EBAY and i got email from ebay seller (unlock fusion) that it is unlocked. So i connected the phone to iTunes and restored it and did not get any congratulations message. I did not put a SIM card in the phone while restoring since i dont have any SIM card. So after the restore got over, i got message saying "there is no sim card in the phone you are attempting to activate" It wouldn't work over Wifi as well as it asks for SIM Card. How should i make this work ? Should i get a tmobile sim card (i want to use tmobile) and out inside the phone and again try activating it ? Since i did not get any message about whether the phone is unlocked or not, i have no idea whether it is unlocked or not. But as per the seller it is unlocked. Before the restore the phone was working fine (without SIM) so i believe it was originally activated by previous user on AT&T. In this case do i just need ANY SIM to do the activation ? It need not be AT&T SIM right ?
