So I know Verizon's network is better than AT&T's. I currently have Verizon and get amazing service pretty much everywhere. The question is: how bad is AT&T? Do they really have the fewest dropped calls? How often do you have a dropped call or lose service in your home or office? That's what I'm really worried about. So, who dropped Verizon to get the iPhone and was it worth it? I would especially appreciate input from those of you in the Bay Area (I'm in Redwood City). Thanks!
