I need help! I'm on my third bluetooth headset--a Plantronics Voyager 520. When I first bought it, the treo and headset worked fine. However, now I'm unable to get audio through the headset even when they are paired (little headset icon is there). I think it started after I charged both the phone and headset. I've checked the various settings-- they are paired, it's a trusted device, type: audio. I've paired again and again. Has anyone else had this issue? Any suggestions on how to resolve?
