At&t, At&t Data Usage | featured news

Mike Trang likes to use his iPhone 4 as a GPS device, helping him get around in his job. Now and then, his younger cousins get ahold of it, and play some YouTube videos and games.

On Sunday, AT&T is reconfiguring its mobile data plans in way that will anger many customers but may actually please others. It’s raising its smartphone and tablet data plan rates, while simultaneously offering customers a better deal on the data they do consume.

An MSNBC investigative report, and related lawsuit, claims that AT&T has “systematically overstated” the data usage of iPhone and iPad customers. Lawyers for the plaintiffs, seeking class action status, hired an independent computer firm to compare the actual amount data used by iPhone and iPad customers with the amount that AT&T bills users for.

AT&T said it will introduce "incentives" to encourage iPhone customers to cut back on data usage, as it battles growth in wireless traffic and perceptions of network problems.
