There's the
XDAndroid wifi tether app.
There's Barnacle wifi tethering, on the Market.
My personal fave - the built-in wifi tethering works fantastic, and is the only one I've found that creates a REAL AP to connect to!
Does your regular wifi work? Assuming that does, I would think the built-in wifi tethering works.
I use it on FRX05 all the time, works great. I'd assume the other builds work, but I have not a clue as I never run them for more than 10 minutes
