I have the Tytn running on T-Mobile and I'm in Europe for two weeks. The phone is picking up UMTS and beyond my general concen for cost because it's picking up UMTS, I'm finding that the UMTS signal is not that strong in certain locations and would rather it stay permanently on EDGE. Anyone know how to make it stay on GPRS/Edge and not UMTS? I've tried the manual selection, but it not's workin.
