AT&T must really be scared. First, they start giving some of their current customers the option of unlimited data. Now they are offering unlimited mobile to mobile. Which I must say is very impressive. I came from the lowest Sprint plan with mobile to mobile and never came close to going over minutes. All this iPhone competition is going to give us, the consumers, a lot of better and cheaper options. Hopefully Verizon will follow suite. The iPhone 4 on Verizon really does change everything, again.
