Complaints over Apple Inc.'s use restrictions and recent software update for the iPhone have erupted in two lawsuits.
The suits accuse Apple and AT&T Inc. of engaging in illegal monopolistic behavior.
Two separate lawsuits were filed in San Jose on October 5th.
One was filed in federal court and the other in state court and both seek class-action status.
Both cases accuse the companies of unfair business practices and
violations of antitrust, telecommunications and warranty laws.
AT&T is the exclusive carrier in the U.S. for Apple's iPhone.
The federal lawsuit alleges that by not allowing other carriers to serve the iPhone, the two companies conspired from the beginning of their partnership to maintain a monopoly.
Apple has sold more than a million iPhones since it hit the market on June 29th.
