    I'm on an iPhone 3GS with the iPad baseband (6.15.00) and I believe my bootloader is 6.4. My model is MC137LL (32GB black 3GS) and I am currently using a custom firmware from Sn0wBreeze, but UltraSn0w 1.2.2 still yields "No Service"
    I'd like to know if I'm able to unlock, and what I need to do to do this. If I can get some clarity and my phone working and unlocked (AT&T GoPhone SIM) I'll be glad to send a thank you via PayPal.

    I did, from what I understand that solution applies to T-Mobile users but I tried it anyway. Thanks for the reply by the way.
