Personally I don't tether,other than seeing if it worked, because I have no need to. There is nothing I need to tether that doesn't already have an available wifi connection. That said, if I did have something to tether would I? Probably would, and I wouldn't really feel all that broken up about it. I still doubt VZW can tell and even if they can there will be a work around to hide it anyway so it's a loosing battle for people that root and hack their phone. However, VZW will shut down non-paying tether use by most new buyers and current owners that don't already use one of the market apps just by removing them because most users don't look past the android market...
