Mark my words, this will end up as a Class Action Lawsuit. So they have a caluse in there that states you "Cannot Tether". But, it is NOT stealing. If I'm already paying for "Unlimited Data" it should not matter whether that data is being used directly on my phone, or whether or not my phone is being used as a pass thru to a laptop. At the end of the day, it's 1s and 0s. I should not be required to pay a 2nd monthly fee to have this feature enabled on my phone to use an unlimited service that I already pay for.
That's the crux of all this. Yes, there are people paying for it. Does it make it right that ATT is strong-arming them to double pay for something?? Does your home internet service make you pay for every PC, X-Box, Wii, PS3, BluRay Player, whatever electronics device you may have that is connected to that single IP address portal?? The problem is, this is monopolistic. I cannot go to Verizon, because they have the same clause. So in the meantime, until this is all settled, I choose not to tether. I'm using the bajeesus out of my "Unlimited Data" using approved apps from the App Store. If ATT attempts to tell me that I have to stop tethering when I am not, then I will have suitable grounds to generate a lawsuit at that time.
