Over the Bank Holiday Weekend I upgraded my TyTn 2 with the HTC released Windows Mobile 6.1 build.
I upgraded the device on my Vista laptop and it all was done in about 10-15 minutes.
Of course I've been using Windows Mobile 6.1 for a long time now but this is the first publicly available build.
One thing I have noticed is that the battery life on my TyTn 2 seems to be considerably improved. I'll have to see what my experience is like through the week.
If you have a HTC TyTn 2 then head on over to the E-Club to register your device and Download the Windows Mobile 6.1 build!
Have you upgraded your device yet? What is your experience so far?
