Tethering Basics - as in how to? I searched for keywords of tethering and basics and came up with squat. I have never tethered and have no knowledge of how to do so. Is there a quick and easy how to guide in someone's head just dying to come out through their fingers to a keyboard near you? What would I need, HW/SW? How would I do it? Does it work reliably? If I have the 29.99 plan on Verizon, could I do this? Any help appreciated.
