Here is another option that I am using with my Telus Diamond and gmail. Works good but the program is still in development. you loose your settings after soft reset and have to enter your username and password info, but if you do not reseta lot this may work for you. I like that it integrates with poutlook and you see the messages count etc. in TF3D screen.
Hopefully the developer will continue with its development.
