Can't dial out, have signal, WTF

**We87** · 06-03-2010 05:56 AM

iPhone 3GS with fw 3.1.2 and BB 04.26 running Ultrasn0w.

I have restored with a custom 3.1.2 to preserve my baseband, install ONLY ultrasn0w and I have full signal with my T-Mo simcard. However I can't make a phone call, send a text, use the web, etc..... Nothing works. Wifi and every other feature works just fine. But nothing GSM related.

Anybody have any clue what to try next?

Have you turned off 3G? t-mobile in the US uses different 3G frequencies to AT&T so you can only use a 3G or 3GS at 2G (EDGE) speeds
