SAN JOSE, California (AP) — Complaints over Apple Inc.’s use restrictions and recent software update for the iPhone have erupted in two lawsuits alleging Apple and its carrier partner, AT&T Inc., 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.

Apple spokeswoman Susan Lundgren and AT&T spokesman Mark Siegel both declined to comment on them Wednesday.

The federal case was filed by the firms of Hoffman & Lazear in Oakland and Folkenflik & McGerity in New York on behalf of iPhone owners Paul Holman and Lucy Rivello. The state case was filed by Saratoga attorney Damian Fernandez on behalf of California resident Timothy Smith.
