On my HTC Magic, I am able to set, under settings, whether I wanted 3G, 3G/2G, or 2G only. I found that helpful because there were some areas where the 2G signal is actually stronger and more reliable. I don't seem to be able to do so with the X10a. It is either 3G only or a hybrid 3G/2G. When I do the hybrid, the signal in house changes back and forth between 3G and 2G. Does anyone knows of an app that will force the phone to be on 2G only? Thanks. Oh, btw, I noticed also there is an option to disable mms and data. Is that function actually forcing the phone to be on 2G, i.e., GSM?
