There is not much to say about this news except, wow, that was fast, NOT. This update must have been a planned release for maximum effect during CES.
Here is the change log:
OS Upgrade to Windows Mobile 6.5
Updated drivers to support Global VZ Navigator
TouchFLO 3D Enhancements
Also available, after an unofficial leak, is the Windows Mobile 6.5 update to the HTC Ozone.
