The fact is that "3%", which I think is a bull**** figure, is what has increased AT&T Profit by 80% over the past 3 years. How much of that was invested into the network to hold up to all of these data hungry iPhone users you ask? Well, they have spent less on Network Construction each quarter since the launch of the iPhone. How much money have these iPhone uses brought into AT&T you ask? Right around 3 BILLION Dollars a quarter. So, sure. . . I can understand not putting some of that money back into the network to support these phones/users. Especially when the usage is only going to increase as newer phones come out. Makes a lot of sense to me . . . .
