Is your plan currently available for new folks to sign up on? No. Do you wonder why? It is because it was a stupid thing for AT&T to offer. They now understand much better how much bandwidth can be used by iPhones and their customers.
AT&T should just end the plans and switch everyone over. Then you can sue them for breach of contract because you believe you now have an inalienable right to use AT&T's network as much your device and you can manage. You do believe that you have a loophole, hence you do believe you have a free ride. You do believe that other AT&T customers will pay more and you will pay less. If you don't see that you are delusional.
I'm sorry, but you're the one that's delusional. I have never stated nor do I feel that an unlimited data plan is my inalienable right. AT&T is the one that offers it to me every time I commit to a new contract with them, which happens to be every two years in my case. I don't demand it or even ask for it. AT&T offers it to me.
Why should AT&T have a right to advertise and offer me an unlimited data plan, and subsequently not spell out the exact terms of usage in the contract, and then arbitrarily do whatever they think is best? What if AT&T decided tomorrow that 500 mb of data should be the limit before Unlimited data plans are slowed to a screeching halt? It would be no different than what they are doing today. It is not clearly spelled out in the terms of the contract that they offered to me and we both agreed on.
