AT&T is another monopolistic relic. They don't move fast on anything and there's a huge amount of management overhead for even the smallest task. They may very well invest a huge amount of capital into infrastructure upgrades but how much of that actually translates to real world improvements is unknown. I'm not sure Verizon is all that much better off in this respect but they happened to deploy a more scalable technology better suited for data long before the demand was a reality. Going forward with their LTE upgrade we could very well see the same situation AT&T is in.
