LA Weekly is report that a class-action lawsuit has been filed in Los Angeles County Superior Court by a person named Donald LeBuhn, claiming that Apple's marketing of the glass used in the iPhone 4 as "20 times stiffer and 30 times harder than plastic" is deceptive and that the glass is in fact defective. LeBuhn claims that the company knows about the defect, but refuses to warn customers that "normal use" -- which in LeBuhn's case involved dropping the iPhone from a height of approximately three feet -- will cause the glass to break.
