It's not too late to inform you if you haven't catch the update for your Cingular Treo 650. v1.17 was released last week.

The Treo 650 Updater 1.17 offers these performance enhancements for your smartphone:

• Includes VersaMail 3.1c, the latest version for Cingular Wireless Treo 650, which includes an updated Mail Service (ISP) list.
• Adds support for Gmail attachment downloads via web browser
• Optimizes Bluetooth performance for some Motorola headsets and other car kits
• Adds voice quality enhancements.
• Optimizes memory handling
• Correctly saves Auto-off power setting. This addresses an issue experienced by some users after installing updater version 1.15
• Adds an audible beep to indicate call initiation failures
• Improves battery life by automatically turning off screen after 30 seconds of a call (originally included in Treo 650 Update 1.15). The power savings will vary depending on usage patterns. To turn the display back on at any time, tap the screen. Do not press the red Power/End button, unless you want to end the call. The screen-off feature applies to handset mode only, not speakerphone or headset modes.
• Incorporates three software patches previously released on Palm's website:
• Treo 650 Updater 1.15 (released July 2005): Provides non-volatile file system improvements (info); includes "Get Good" application which facilitates faster, wireless installation of Good Technology’s GoodLink email software for business customers
• Carkit Update for Treo 650 (Bluetooth carkit drivers)
• Treo 650 Voicemail Updater 1.04 for Cingular Wireless

Quite a number of updates, get yours now!
