I've gotten about 6.12 down and 1.3 up in Atlanta, GA with 3.5G speeds, matched my brother's MyTouch 4G. But in the city I where I live, which "technically" has 4G, I can only get 1-2Mbps(or at least I did, until speedtest.net stopped working). And what's even better, in the town I go to college in, we only have Edge.
I should mention, this is on T-Mobile US.
