Is AT&T overcharging its iPhone and iPad subscribers?

Uh oh, it looks like AT&T might be in big trouble now. Just recently, an independent investigation took a closer look at the way the nation's carriers were charging their customers for data usage, and the results did not look very bright for AT&T. The research showed evidence that iPhone and iPad users that use AT&T's 3G data services are being overcharged on a regular basis – by up to 300% in some cases.

The entire investigation cost about $80,000 and was conducted by using different carriers and different devices, one of which was the iPhone 4 for AT&T. Even when it was not in use and had every single application that might use data turned off, the iPhone 4 used data 35 times according to AT&T's data usage statistics. The results were quite surprising, to say the least.
