I was 2.1 rooted with WiFI tether woring and updated to 2.2 this morning. When I try to start wifi tether it says "Unable to start tethering. Please try again!" This is from when I press the icon - Press to start tethering. - Any idea? I have done battery pulls, unistalled and reinstalled the app. Tried turning on WiFi before starting up tether and none of these things have worked. this has been the only thing that I have noticed not working, for me.
