I'm shocked at how slow ATT's 3G is. On my Nexus One with T-mobile, tethering to my notebook, I'm constantly getting 6.2Mbps down and 1.8Mbps up and I get unlimited down on my plan as well (well 10GB is the cap really thats what I hear).
I know Att is supposed to upgrade their 3G service by the end of the year though so perhaps it will catch up with T-mobile at the end of this year.
