I'm selling my Sprint Treo 600 as I'm planning to get the 650. I've had the unit since January of 2004, and it has (and still does) worked flawlessly since I bought it. It's in very good condition, with a few minor scuffs/scrapes here and there - the most severe being a slight chip in the plastic on the spacebar key. (although it doesn't affect the usage or functionality of the key at all) Screen is in excellent condition as it's had a screen protector on it's whole life.
Price is $250 (shipping included) which includes the following accessories:
* BlueTrek G2 headset (bluetooth)
* Jabra A210 bluetooth adapter. (this allows you to use BT on the 600)
* Seidio 2100 car kit designed for Treo 600
* 64mb
SD memory card
* standard palm cradle w/ charging cable
* extra A/C charger cable
The accessories are all in excellent condition - the BlueTrek headset and Jabra adapter each have less than 3 hours total usage. (they're probably worth almost $100 by themselves) The Seidio car-kit also works very well, and I'll also include a Radio Shack "tape-adapter" which connects the Seidio cradle to your car stereo's tape player.
I also have the original box/manual for the Treo, as well as the carrying case that came with it. Let me know if you're interested!!
