There are several posts saying that they think ATT has no right to charge more for tethering because you pay for an unlimited data plan. Let's make something (obvious to me) very clear 1. You pay for unlimited for the device you have registered with them. One device. 2. If you had two iphones, you'd be paying for 2 unlimited data plans. Two Devices = 2 Data plans If 1 and 2 are true - you have to accept that allowing tethering is opening up more than your ONE device to their bandwidth for which they have EVERY right to charge additional fees for. Again - you are paying to access the net on ONE device. Tethering allows other devices in ADDITION to your phone to access their network. So... can we stop with all the complaining or implying that ATT has no right or it's stupid of them to charge extra? Look at Disney for example. If I pay for an unlimited 1-day park hopper - that entitles ME to go on all the rides. I can't leave at 2pm and then give my ticket to someone else. If I go to an all you can eat buffet, that doesn't entitle me to take food home, give their food away to other people in the restaurant or worse, go into the kitchen and help myself to whatever they have ...and no. I don't work for ATT nor do I think they are perfect.
