3g iPhone running the latest firmware. Blackra1n jailbreak worked like a charm. But blacksnow isn't working for my t mobile unlock. It trys to read the sim and ends up just saying no service. This is my first time troubleshooting blackra1n... anyone had problems like this and found any solutions?? I've reset the phone. Re-ran the entire process three times, mixing up steps and doing any variations I could think of with no success. Like I said, jailbreak works like a charm, but everytime I try to get the unlock the phone reads NO SERVICE... any help is apppreciated.
