iOS is Apple’s mobile operating system, which runs on iPads, iPhones, iPod touches, and Apple TV. Apple regularly releases free updates and bug fixes for iOS. Some changes add features to iOS and the built-in apps, whereas others plug security holes or fix stability problems. You can update to the latest version of iOS over Wi-Fi.
