what you need to do is get into the service setting. open the phone program and dial ##778# or whatever it is for your provider. I have a different dialer skin so that is what I press. then tap edit, enter 000000. once it comes up to the next screen press view info then select M.I.P default Profile. then the 3rd line down you should see DUN NAI. highlight it then press menu, edit then enter your username for your data network. (it should be the same setting as the NAI above it) then press ok, ok to reboot. then tether away without paying the ridiculous tethering fee. my only suggestion is keep it around 5GB a month or they might start investigating why you are using so much data.
