how can I know if my baseband has been modded?
I bought my iPhone from a guy on eBay which he claimed it was unlocked. the phone arrived so I inserted my sim and all but it didn't get recognized by the phone so I tried to unlock it myself but instead I made a mistake and upgraded the firmware to 1.1.1. then I explained the situation to the seller and he told me you had to make some dialing attempts then the phone would have recognized your phone. Now I have 1.0.2 unlocked with IPSF and wanna upgrade to 1.1.1 but wanna know if that guy has really modded my baseband or he was scamming me and even didn't attempt to unlock the phone. Is there a way to find out if he's opened the phone or tried to unlock it with anysim or iunlock??
would appreciate your support guys.
