"Apple should leave AT&T"
Limitations too much to list here. Data caps on tethering is foremost. Pros: nice apps, battery life a little better,lots of memory
Cons: slow, bad reception. no multi-tasking, no turn by turn, dropped calls, i would of gave it 5
stars if it apple was with another carrier Apple and AT&T are not working together well. If you're in the US you can't use the new picture messaging feature because AT&T is not supporting it. Also I am now going to go on to my 3rd 3g s in two days. My year old original phone is better.
