Do you know what hardware version you have on your Q? MOL1, MOL2, MOL3?
Your options are:
MOL1 : ##32.... I forget the number, but you can search for it and there's a step-by-step how-to to tether your Q the "old" way.
MOL1-MOL3: Pay $34 for
PDAnet. Greatest investment I have ever made. One time fee, and provides ActiveSync and BT DUN
MOL1-MOL3: The most "ethically correct" method is to call VZ and ask them to add the $15 tethering plan. You can add it and remove at will so if this is a one-time occurance, it's only $15 -- over 50% savinngs on
PDAnet. However,
PDAnet pays for itself if you are a mobile professional. I myself find having my oil changed one of the most productive hours of my day since I just go into the waiting room, log into work in a distraction-free environment, and bang out what I need... most of the time my car is ready sooner than I would like it to, but you can't win them all
