suraj.sun writes in about the recent small claims case against AT&T's throttling of 'unlimited' plans. From the article: "AT&T has about 17 million smartphone customers on 'unlimited' plans, and has started slowing down service for users who hit certain traffic thresholds. Spaccarelli maintained at his February 24 small-claims hearing that AT&T broke its promise to provide 'unlimited' service, and the judge agreed. In a letter dated Friday, a law firm retained by AT&T Inc. is threatening to shut off Matthew Spaccarelli's phone service if he doesn't sit down to talk. Spaccarelli has posted online the documents he used to argue his case and encourages other AT&T customers copy his suit."
