I just got off a call with my wife (SV to the Bay Bridge, iPhone to iPhone) and it only dropped 4 times.
I just relocated to my number to SV a couple of months ago and I only had to call 4 times to get all the features back to what they were. Plus I got over being mad about having no message at all for callers to my old number.
Also, I really don't mind calling AT&T every couple of months to find out why that charge was on my freakishly high bill. I love the way all the call center people are trained to take an extra 15-30 seconds per call expressing AT&T's caring attitude. That script doesn't need to be shortened at all.
I never wonder if an unemployed poor person on a pay-as-you-go plan has lower costs and fewer customer service problems. And I got over the shock of the difference between the high margin Apple experience and the high margin AT&T experience. Really, I have.
Nope. AT&T has nothing to worry about.
