Can I just get some thought about which phone is an over all better phone. I use AT&T as my carrier, I have both the 8310 and the 8320 unlocked. Ive heard from some people that the 8320 will not work as well on the AT&T network, is that true? and if I use the 8320 should I install the AT&T software on the phone or keep the TMO software on the phone.

I understand that the 8310 has GPS and the 8320 has wifi, but can the wifi be used with the AT&T software and can someone say one phone is over all a better ph or is both just the same with those two differences?

Any thoughts would be great.

Thanks,
