Also remember that on Verizon you won't be able to call and use data at the same time (something I do a lot). I'm in Houston and luckily haven't had the bad experiences with AT&T many have. I now have 4 iPhone 4s in the house, and will wait for at least a year to see what happens on Verizon. All of you jumping over to Verizon should help increase AT&T's bandwidth anyway.
