AT&T Mobile Share Data Plans Launch August 23rd, But Are They The Best Deal?

AT&T charges quite a lot to add each device, and the data pools are predictably pricey. Granted, data seems to be getting more and more expensive while voice minutes becomes less and less desired, but still -- do the math for your own personal situation before buying in.
