iOS 5 turns Japanese iPhones into earthquake alarms

Following the devastation wrought by the new Japanese earthquake , Apple has hooked the country’s early warning system into iOS 5 . The tectonically-volatile nation has the foremost sophisticated alarm on the earth, delivering life-saving warnings seconds or minutes before disaster strikes. iOS users already had access to this functionality via apps like Yurekuru, but iOS 5 will bring it directly into the operating system. The service could be activated within the Notification Center settings pane, accompanied by a warning that the constant connection will deplete your battery faster — a good exchange if it saves your life.
