For about $400 I got a Nokia E72 that will work on all 3 3G frequencies (850, 1900, 2100 I.E. Tmo and ATT, as well as overseas) and it has VoIP abilities built in, I Would have loved one of the google phones but no ATT 3g and it's/their selling for more then the E72 made it easy choice.
Nope, that E72 will not work on T-Mobile in the US.
