Ok, I take good care of my Treo 650 (avoid dropping it, water, etc.) yet I am putting in my phone for the third advance exchange. The first time, and now the most recent time, my in-handset earpiece has stopped working. Callers can hear me clear as day, but I can not hear them at all. Is anyone else having this problem?!? I know it is nearly criminal to say, but I am considering going to a Blackberry if Palm doesn't figure out the problems soon.
