I'm pretty torn because even though I can get up to 3-4 times faster data speeds on ATT, VZW is much more consistent and stable. Sure I can run a speed test and hit up to 5mbps sometimes but if I download a large file it'll never hold that speed regardless of where I am in LA/OC. There's also a lot more ATT deadzones around here. I guess it's more of a problem if you are using data on the go (navi, stream music, etc...) or frequent fringe areas. Call quality is also definitely worse and I've seen more dropped calls since I've switched to ATT (last june) than I ever had before. Funny because my girlfriend went from ATT to VZW and I did the opposite for the iphone 4. Now I know what she was always bitching about ha. I guess I can still show off my speed tests though
