I don't use AT&T. But I was listening to a CNet podcast today and they were talking about AT&T having terrible network problems because of the iPhone.
Apparently iPhone data use is close to bringing AT&T's network to its knees. AT&T's senior brass are looking at rate increases on data to deal with the problem.
An interesting fact ... something like 3% of iPhone users account for 40% of all data traffic on AT&T's network.
