I have a Treo 680 and my housing was cracked badly, so i changed the housing. I followed all directions and i put it back together. Now I can hear the sound when it comes on, it rings, everything works as normal except when i receive a call the caller can not hear me. so now i can only talk on my phone through my bluetooth or headset. Can Someone help me please !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!:eek: ...
