I have an AT&T iPhone 4 on iOS 5.1.1 9B208 locked to that carrier and I don't have an AT&T SIM and can't get one because I no longer live in the States. I'm stuck on the no SIM card screen and I tried to hacktivate it with Sn0wbreeze 2.96 and got all the way until the iPhone was put in Restore Mode and iTunes was extracting but I got a 3194 error. My iPhone is still currently in Restore Mode (black screen), please help me . I really want to start using my phone .

Also, i want to add, I'm a complete noob at this and I'm desperate to finally use my phone. I want to unlock it to be able to use it with any GSM carrier. Please help!
