I've got a new Treo 600 for the ATT GSM system and a Vaja iVolution case for sale. The Treo is a replacement ubit from PalmOne; the original plastic is still on the screen. Case is gray on the front, black on the back. Charger included, with headphone adapter and coiled headphone. No SIM card.

Asking $350. E-mail me if you're interested.
