this is new to me... I never tried internet sharing til today.
anyway figured i'd give it a try.
With the new rom 3.35 All I had to do was(using win XP MCE with SP2).
shut off wifi(on phone and notebook),Plug in USB cable.
on phone:
Programs>InternetSharing>(verify pulldown is USB/Phone as Modem)
>connect
Phone Dials 777, Status then shows connected .... and was able to use notebook no problems.
Actually pretty decent connection...
