While the Windows Mobile version has hit a bit of a snag, the version of the Nokia N810 seems to have come on great, and the Mozilla team is readying a beta for the device soon. This video below shows the app in action, and it looks pretty good.
The latest news from the Windows Mobile Fennec team is that they have sorted out their memory allocation issues and are just about ready to move ahead. They have also implemented GPS and telephone dialler support.
Hopefully the Windows Mobile version can now also move full steam ahead and add to the already large library of great Windows Mobile browsers.
