I saw this in an email I received from palmOne. Below is a description of what the update fixes. - Enables Bluetooth Dial-Up Networking (DUN) so you can use your Treo 650 as a modem for your Bluetooth® wireless-enabled laptop (requires appropriate pricing plan from Sprint) - Adds support for additional Bluetooth carkits including Acura, BMW, Chrysler, and Toyota Prius (see all compatible car kits) - Reduces post-dial delay before a call is connected - Provides additional ways to send SMS messages from the Missed Call Alert or Call Log - Updates VersaMail to version 3.1 - Includes previous enhancements from the March 2005 1.08 update To download the Sprint software update, visit Customer Support today!* Unfortunately I'm not on Sprint so I can't tell you how well it works. I would definitely recommend reading all instructions before performing the update. Glenn
