3G 3G 3G....
Absolutely horrible data speeds. I'm talking as low as 34kbps down, and 19kbps up; never broke 450 down or 350 up. My Evo 4G consistently does 1500-2200kbps down, and 600-900kbps up in the areas I tested. I'm not sticking around to see if it's an individual phone issue, or if HTC botched the antennas on the whole lot. Mines going back to Sprint next week.
At this point, I'll wait for the SGS III, and see if the Evo LTE is about to have its own antenna-gate.
