Back in January we noted that AT&T was facing a new class action lawsuit accusing the carrier of over-charging both iPad and iPhone customers for data. According to the lawsuit, AT&T not only artificially inflates actual data usage estimates anywhere from between 7 and 300%, but the company bills for data when the phone or tablet is disabled or unused. With AT&T recently getting the green light to bury fine print in user contracts banning customers from participating in such class actions, that case is now heading to arbitration. AT&T and other ISPs prefer arbitration because the arbitrators are generally companies hired by the ISPs, who -- at least based on data in the credit card industry -- tend to rule in favor of their employer 94% of the time. The original suit sought restitution and class damages for breach of contract, unjust enrichment, unfair and fraudulent business practices, unfair competition, and violations of the federal Communications Act.
