Apple now claims an error in the iPhone 4 firmware is responsible for the dramatic drop in signal bars some have experienced when the device is held a certain way. An update for iOS 4 will be released in the coming weeks to address the problem, but in the meantime several lawsuits have been filed against Apple over the issue.
The most recent suit was filed Friday in the Northern District of California and accuses Apple of false advertising, breach of warranty, and unfair competition among other complaints. The plaintiff, Steve Tietze is seeking class action status for the case and contends that Apple is guilty of "misrepresenting and concealing material information in the marketing, advertising, sale, and servicing of its iPhone 4 - particularly as it relates to the quality of the mobile phone antenna and reception and related software."
