I've been reading all the posts regarding T-mobile, Cingular, and AT&T this past week, and it seems like service has indeed improved with Cingular with T-mobile not far behind. My question is, which provider is #1 at the moment in terms of coverage/reception for the Bay Area? It still looks like AT&T TDMA has the best coverage. So, my next question is, with all companies focusing on GSM now, would it be smart to switch now to Cingular or T-mobile or stay with AT&T. I still need good service since I travel quite a bit around the Bay area, and I don't want several months of poor service with Cingular/T-mobile just to jump on the GSM bandwagon.
