Hi, I have on me a 3GS with 5.0.1 and 6.15.00 BB.
Now it's jailbroken and i've installed ultrasn0w 1.2.5. after reboot any simcard other that T-mobile UK causes the No service to appear. I've checked the about and under network it shows the correct network for the inserted sim, but it just doesn't want to get passed the no service problem. I tried reflashing the iPad baseband onto it, but it still didn't help.
any ideas and tips would be appreciated.
