Complaints over Apple’s use restrictions and recent software update for the iPhone have erupted in two lawsuits alleging Apple and its carrier partner, AT&T, engaged in illegal monopolistic behavior.

Two separate lawsuits were filed Friday in San Jose–one in federal court and the other in state court and both seeking class-action status. The federal case accuses the companies of unfair business practices and violations of antitrust, telecommunications and warranty laws. The state case raises some of the same allegations.
