Apple’s iOS5, which has over 200 functions such as iMessage and updated alert functions, is going to add an earthquake early warning function on Japanese phones. It is linked to the Japanese government’s early-detection service, which can provide a few seconds advance warning prior to an earthquake hitting. The earthquake early warning function can be activated or deactivated on the Notifications pane of an iPhone’s settings.
If the warning function is left on, the battery will require charging more often. Apple iOS 5 will ship in the fall to the following devices: iPhone 3GS and iPhone 4, iPad 1 and 2, and iPod touch 3rd and 4th generation
