I think this may be my next step. I first wanted to go back to the stock rom to see if the problem occurs there. If it does, I'll start playing with the radio. It's frustrating because when I'm testing it 5-6 calls in a row will work, then i'll get 3-4 that don't work. For a while I thought it had to do with using ActiveSync but it doesn't appear that's the case as I've gotten it before running activesync as well. It's just so hard to pin down but it seems like an odd problem to be a hardware issue as I show full bars the whole time so it's not like my antenna gets disconnected or anything?
