I noticed my EVO is running sluggish (2 second delay when touching screen) after the recent upgrade (not 2.2), but the most recent upgrade. I'm trying to figure out why? Right about the time I upgraded the software, 4G was becoming more available in my area. so I'm trying to figure out why my EVO seems to be slower in regards to previous upgrade/4G. Those are the only things I can think of that would cause this...and of course, I'm probably wrong.
