    Hi! I have a 3G running 3.1.3 OS. It locked up after a Rock upgrade so I had to re-jailbreak and unlock with redSnOw. I had previously used Blackrain but that did not work with the new ITunes upgrade. So, all seems ok except the phone will NOT read my T-Mobile SIM card. The card does work in my Blackberry. I also tried my hubsband's card and it did not work.

    Any suggestions??? Thanks!!!!

    What is the baseband version(modem firmware)? If it's 05.12.01 you can only use the phone with an official service provider.

    RedSn0w does not unlock.
    Which country are you in and who is the phone locked to?
    He who asks a question looks foolish for 5 minutes. He who doesn't ask a question remains foolish forever.
