An AppleInsider report notes that Kliegerman and his lawyers make the assertion that had AT&T allowed him to purchase and use a SIM card from a foreign wireless carrier, "he would have been able to utilize iPhone internationally at fees substantially less than the $2,000 charged by AT&T." The suit seeks an injunction forcing Apple to sell unlocked iPhones, and provide unlock codes for all current owners. In addition, it seeks to force Apple to disclose international data roaming fees more adequately to customers. Earlier this month, Apple was slapped with another class-action lawsuit over the battery in its iPhone, by a Northern California resident who echoed claims of a similar suit filed in the state of Illinois. Sydney Leung accused both Apple and AT&T of fraud because the companies neglected to inform potential iPhone buyers of the costs related to maintaining a working battery for the device over the course of the iPhone's lifespan.
