Everything was working great. I virginized then upgraded to 1.1.1 then I jailbreaked with touchfree (beta since i used iunock on 1.02)and everything works great but I can only call using my att sim.

WHen I try my tmobile sim I get almost no signal and in settings/carrier it is grayed out. I can not select anything. I have Automatic, T-Mobile and AT&T but I can not select any of the three.

Help is greatly appreciated.
