When iOS 5 for the iPhone, iPod touch and iPad is released later this year, it will include a tie-in to Japan’s earthquake early warning notification system. Earlier versions of iOS don’t include the feature, making iPhone owners in Japan rely on third-party apps for earthquake alerts.
iOS 5 to include early earthquake warning support in Japan
Users will be able to choose whether or not they want to enable the feature, according to 9 to 5 Mac, just like other iOS features such as Location Services.
Apple said iOS 5 will ship this fall, but hasn’t announced an actual release date yet. The update is, however, generally expected to roll out some time in September or October along with a new version of the iPhone.
