    Default 3GS Cant Unlock, Keep getting No Service
    I have a 3GS New Bootrom, 4.1 formware, 6.15.00 baseband. I tried unlocking it every possible way but all i get is No Service. I tried custom 4.1 firmware, upgrading it to 4.2.1, but nothing I do works. Anyone know what might be the problem? I use redsn0w to jailbreak and ultrasn0w to unlock

    I have seen people have some success using an older version of ultrasnow (1.1-1)

    Just google for it, once you have it you can stick it in the autoinstall folder of cydia using a usb file explorer.

    It is at var/root/media/cydia/autoinstall I believe

    You can use something like ifunbox to put the .deb there

    I don't know what else to try sorry, there was a thread around here with others with this issue. Don't know if that would help.
