Trying to find help unlocking iPhone. I just purchased one and have tried everything. I even bought iPhoneSimFree and try using Simfree V1.8 to unlock my sim card but there is alway an error when connecting like "Unlock Failed. Error Baseband Communications." so now I dunno what to do. Any help would be VERY appreciated. Firmware says 1.1.1 but I have iTunes. Using windows.
