Right now I'm on AT&T GSM in the SF Bay Area (San Jose specifically), and I absolutely hate it. Dropped calls, poor quality, calls not going through. I'm fed up, and want to switch. I'm considering T-Mobile, they seem to have some good deals I was looking at. Any opinions on their quality in this area? If they are no good, what about Verizon in this area? I just want a damn service that works. With AT&T I can't get a signal at work, in my apartment, in most malls, on customer sites (I do a lot of service calls), and various other places.
