I haven't used this in a couple of years, but it worked fine then, and appears to be working fine now. It's not activated, so I can't make a call nor test internet access, but it does connect to the Sprint network with no problem.

If it doesn't work right, I'll be happy to refund everything except shipping charges. Includes:

Sprint Treo 600
standard USB / AC Charge cable and charger
standard slip case.
Cradle (don't remember if this came with the phone or not)
Aftermarket AC charger w/ sync calbe
Two cigarette lighter charge cables
USB Charge / Sync cable
Treo external keyboard
Treo horizontal case w/ belt clip (never used)
Software CD

$75 + actual shipping takes all
