ThumbLink, a facebook interface for Windows Mobile, Version 2.0 has just been released. It is designed to be usable with one thumb, allwing you to flick lists up or down. You can see your friends and their status, view and create albums, and even upload photos.
Version 2.0 adds support for non-touchscreen phones, and will update your contacts with their facebook photos where it can match the name.
It's only $4.95, and you can see a demo video here:
