Apple sued over iPhone 4 power button failures

A class action lawsuit has been filed against Apple for iPhone 4s with defective power buttons. Filed by a Florida woman, the suit claims Apple knew about a flex cable defect controlling the power button but kept quiet about the problem to sell more phones. Apple discussion forums regarding the power button are cited as evidence. The lawsuit claims that the part often fails after the phone’s one-year warranty expires. [via GigaOM]
