I recently got the Treo BT headset, so I have two identical adapters and only need one. This adapter connects to your Treo, headset, and whatever else uses that funny connector. I will also throw in the screen protector that came with the Treo 650 (cheap one, but I don't want to throw it away). E-mail me and name your price : peepisklak@hotmail.com. Pay me through Paypal. Thanks!
