Cant find signal after 3.1.2 unlock

[Strategy]

Hey all,

My phone has been jailbroken since last year using blackrain. Im trying to install ultrasn0w via cydia to unlock it but after its installed it can no longer find the AT&T service. Ive tried resetting network settings but nothing seems to work. Any ideas?

3.1.2 with baseband 5.11.07

Ultrasnow does not work with your baseband.
Remove it and install blacksnow thru cydia. That unlock will work for your bb 05.11.07

Thanks a lot, worked great.
