i made the switch from ATT to tmobile just for their 3g and better rates (ie: $5.99 internet plan) but where i work, their 3g signal can't seem to penetrate the office walls, as i'm always on 2.5G in my office. also at home, i get zero reception in the garage, and 2.5G in my room but once i'm outside of the house, its back to 3G. If only nokia went with att 3g frequency, i will be heaven.
