iOS 8.1.1 is compatible with the iPhone 4S and newer iPhone models, iPad 2 and newer, and the fifth-generation iPod touch. The update has a build number “12B435.” The update is available over-the-air through the Settings app under General and Software Update. It does not add any new features but receives a number of performance enhancements.
The update can be received by going to “Settings > General > Software Update”. In September, Apple released iOS 8.0.2 to fix cellular and Touch ID issues.
