My provided headset does not seem to be working. Rather than waiting to order a new headset from Handspring, I thought I would find out if you guys had any recommendations for good headsets to use with the Treo 600. Any problems with compatibility?

Also, has anyone experienced a problem where both the headset jack and the handheld's built-in earpiece both stop working and you can't hear any audio? That recently happened to me, the only way I could hear a caller was over the "speakerphone" and I had to replace the unit.

thanks,
