If you're looking for a Treo 800w audio adapter, don't buy...the "OEM Micro USB to 3.5mm Adapter for Motorola RAZR2 V8 V9" from Ebay. I gave it a shot, thinking that it could work since it's a micro usb adapter...no such luck. The cheapo power adapters i got do work though (and only $1.99 at that!): http://www.hitechcloseout.com/store/...0&cat=0&page=1
