AT&T was one of the first to start this. Sometime this month I know Verizon is going to do the same thing. TMO is also going to tiered data plan. The only carrier that has not spoke up about this is Sprint. I wish I still had Sprint, 69.99 a month for unlimited everything. If you have Sprint, get on it. Not to mention the new Android flagship, the Evo 3D. I'm an Android junky and follow around all the carriers and phone hype.
