Apple has decided to do something about the earthquakes that strikes the tectonically-volatile nation, Japan. Japan has the most sophisticated alarm in the world, delivering life-saving warnings seconds or minutes before disaster strikes. The latest Apple’s iOS 5 will hook into the country’s early warning system to provide alerts to the iOS users. It is to be noted that 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.
