I did as was suggested and left tethering on while updating. It was actually there when I finished updating to 3.1, but then when I went to try and tether...it just disappeared!? It was there one minute after the update then it was gone. Tried to re-download the Benm.at file. No luck! Even tried to download the IPCC file and No Joy there either!
I guess I will just have to wait until the Benm.at file gets updated fro 3.1. I checked the website and they said that they were working on it.
