I have an official AT&T SIM, but i also installed ultrasn0w just to try it out with my friends Tmobile SIM (worked so easily!). Should i uninstall ultrasn0w do you think? my AT&T SIM has been working fine with ultrasn0w installed.
dunt mean to bump up an old thread but I need this as well. I have try both bosspref and sbsetting and ultrasn0w all latest version and they are all the same. always stay red no matter if i respring or reboot
