iOS 5 turns Japanese iPhones into earthquake alarms
Following the devastation wrought by the recent Japanese earthquake, Apple has hooked the country’s early warning system into iOS 5. The tectonically-volatile nation has the most sophisticated alarm in the world, 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 can be activated in the Notification Center settings pane, accompanied by a warning that the constant connection will deplete your battery faster — a fair exchange if it saves your life.
