I live in Richmond and picked up the EVO on release day. Surprisingly, I've had 4G since release day. The guys at BB told me that 4G was due to be officially activated on the 26th but the frequently start it earlier. The signal is better now than it's been before.
On a side note, I did the update yesterday and my battery life is better.
Does anyone know anything about 4G coverage on the Southside? Specifically Chesterfield, Hull St area?
Download the Sensorly app onto your phone and take a look. It shows block-by-block coverage for 4G (and 3G). The online map at their website does not have many levels to drill down. THe app has like 16 levels to zoom in.
