Hi, I've jailbroken and unlocked my iphone 3G (4.0.2) with Ultrasn0w, but I still get the NO SERVICE message on the top left. I want to use Tmobile (US).
Reinstalled Ultrasn0w through Cydia several times, toggled airplane mode on/off, reset network settings, disabled 3G, still NO SERVICE.
I'm stuck and don't know how to proceed, please help me.
Thanks for your help!
