Thanks BRosenow, that is the problem I believe, however Verizon wouldn't take my phone back when I first talked to them about it a long time ago. They said that the little test strip for water was too red, and they wouldn't take it back (this is less than half-way colored, obviously not submerged, but too red apparently). Buying a new Imagio or even paying for a repair with WinPho around the corner seems silly.
I am hoping to find a software solution that can deactivate this jack, but haven't found one yet.
Good news is it has started ringing again!
