Can we say Palm Pre plus.... With that said all rooted people know to unroot before going to stock. Second you do not have to be rooted to tether. And as far as tethering there is a lot of back and forth about it. The only way that vzw know 100% for sure you are tethering is if you tell them or hand them your phone with tethering app in the drawer or on the home page. I also believe common sense should be used. Basic use such as sites you go on with your phone ok; downloading movies....I would not recommend.
