Just got my Incredible and love it. I charged it up last night for the second time. Turned it on this morning and all looked good. Received a call this morning and I could hear the caller but they could not hear me. Several more incoming calls and the same issue. Then I made some calls...I could hear the person but they could not hear me. Finally turned phone off and back on and it is now fine. Mute was not on.....anyone know what this could be? Thanks
