My Girlfriend bought a 2G iphone she was told was unlocked and its not. I dont have a problem trying to unlock it as Ive unlocked mine before. My problem is that I have no idea what firmware its currently running on her iphone. Connecting to itunes only gives me an 'incompatible sim card' page and no info or options of any kind. And it wont connect at all without a sim card. Is there anything out there that will tell me what firmware its running?
