I've had the evo about a week now and in area that should get good 3g and 4g coverage. But since I've got it I've had 2 dropped calls. I usually have about around 4 bars of signal but sometimes for no reason it will drop down to nothing for a few seconds and drop a call, happened twice in the last week. The problem is I've had a blackberry for 2 years before this at the same location and don't remember ever having a dropped call. Could bb just have better signal strength? or i am just over thinking the whole thing
