HTC has just released an upgrade for the HTC TyTn II phone that takes it up to Windows Mobile 6.1 Professional. If you have a original, unlocked HTC branded phone, you can head over to the HTC eClub and sign in to get the upgrade which weighs in at around 67 MB. Remember that the upgrade is shown only if you register the phone by using its serial number at the site. Which also means if you have an operator supplied phone (ATT Tilt, Orange, etc.) this upgrade will not work for you.

Windows Mobile 6.1 Pro has a few new features:

• Threaded SMS
• Improved battery and bandwidth usage with Direct Push on Exchange 2007 SP1
• Auto complete for Messaging
• Page Overview mode in Pocket IE
• Zoom Level instead of Text size in Pocket IE
• Phone book contact exchange over Bluetooth
• Support for System Center Mobile Device Manager
• HTC improvements for orientation rendering - although it still takes the same time, it feels faster since it uses a buffering mode

Unfortunately, this still doesn't have the video performance upgrade that everyone hoped it would have. But in any case, this is an important upgrade to get if you have a TyTn II.
