Pocket PC Phone headset adaptor

One of the things that has always bummed us out about the Pocket PC Phone is that you couldn't really just use another headset or headphones and still be able to listen to music and/or chat on the phone.
You can thank proprietary pinouts, but the folks from PocketPCTechs have a pretty handy all-in-one 2.5/3.5mm jack accessory which seems to solve all that, and not a moment too soon.
