This. Are there any actual reports of AT&T following through on their threat? Like someone got the notice, continued tethering, then next month they were on the $45 4gb tethering plan or something.
I still have yet to see a post of someone getting "forced" into the tethering plan. It's been months and people have gotten multiple notices but still don't get switched over. I think AT&T is still bluffing on this one.
