I am thinking of buying a Xoom. I don't want to have to pay an extra $30 per month to have another 2Gb data plan on top of my 2Gb data plan for my phone. I don't want to have to pay $20.00 per month to be able to tether my already limited data Droid X. I would only use the tether to support my xoom when I am on the road. I have limited knowledge of technology, but am savy enough to be very dangerous. What I want to know is what is the best way to be able to tether a xoom to a Droid X as of 7.20.2011. Is there a good way to do it without having to root the phone. Thanks for your help.
