I'm planning on implementing this after the upgrade to the newer software.
I'm in testing right now. I've found a mod for the upgraded software that auto detects mobile devices and pushes a special light version of the forum.
For now, try using the RSS feeds. You'll find RSS links for each forum on the main index of all the forums. Just copy the URL down and enter that into your mobile device RSS Reader.
Also, check out the "Archive" the link is:

This upgrade is a MAJOR upgrade and I've set up a DEV forum to test everything. It's still a few weeks away.
