Palm has released a new ROM update for the Treo 680 smartphone on the AT&T (formerly Cingular) network. The update includes a number of previous updates, and adds improved power management, bug fixes and updated AT&T branding.

Palm provides an installer for Windows XP users, and provides instructions for using a blank SD card for Mac OS and Windows Vista systems. Palm recommends setting aside 30 minutes for the update process. When completed, the update brings the 680’s firmware version number to R01.34 and the software to Treo680-1.09-ATT. BlackBerry Connect and Good Mobile Messaging users will need to re-install each product after performing the update.
