Apple's iOS 9 is now trickling out to your iPhone and iPad, and the big update brings a smarter Siri, public transit directions to Maps, true tablet multitasking and new built-in apps.
iOS 9, and iOS 9.1 beta for testers, has improved stability, a smaller download size and legacy phone and tablet compatibility. That older iPhone and iPad you have works with this update if it runs iOS 8.
New iOS 9 features consist of redesigned built-in apps and a few new ones. There's more multitasking functionality than ever for iPads, while 3D Touch and motion wallpaper are coming for new iPhones. That will make new rose gold iPhone 6S color really pop.
