Handspring is now taking orders for the Treo 600 line of smart phones. You can order your Treo 600 directly from the company's web site at www.handspring.com. They are only offering the CDMA version from Sprint at this time, but the GSM/GPRS version is expected to start shipping soon.
The cost for the Treo 600, without a contract is $599. With a new one year agreement the prices drops to $499. If you want to make a longer commitment, you can get it for as low as $449.
Handspring also made available the details of their Treo Upgrade Program. If you have a Treo 180, 270 or 300, Handspring is offering a upgrade discount.

The offer is only good for Sprint at the this time, but will be made available for other carriers when the devices become available.
