Walking out of the Arclight theater, Sunset and Vine area, and picked up a strong 4G signal for blocks around there (including right in front of the Verizon store!!). Not sure if it was temporary, but will try again when in that neighborhood. No 4G signal in Silver Lake/Los Feliz area closer to home though. Boy was it fast!
Maybe I'll have to head over that way and check it out! My cable internet at home is being really spotty right now, so I'm using my EVO for 3G tether and it's slow. I need my 4G!
