We'll be installing iPhone OS 2.1 tonight and making sure TouchFS has no compatibility issues. An update will be coming out within the next two weeks, including iTunes approval time.
Famous last words apparently. I'm unable to upgrade to iPhone OS 2.1 due to some "issue" I'm experiencing. A ticket has been opened w/Apple and they're looking into a possible solution.
Until this is resolved, we'll still be updating TouchFS, but won't be able to test it on 2.1.
