Audiovox PPC-6600 / PPC-6601 / XV6600 (HTC Harrier)
Accessories
www.boxwave.com has the mini-sync cable and the adapter for car and wall available. looks like they built it from the spec from the OEM (HTC). I ordered the USB sync/power cable and the versa charger and will have an update when they get here. I got a notice that they shipped today.
I have not been able to find the extended battery so may have to wait for the retail release.
