I used to have unlimited data on my iPhone but ditched it for 15GB and unlimited talk and text (wife and I split) and its 15 bucks less than we were paying a month and she used to have line 350mb of data. They would not allow me to tether with my unlimited data. Now I don't know if that got lifted or not for grandfathered plans. But I use my tethering all the time with my laptop and it's great.
