Apple released iOS 8.0.2 to the public Thursday night, addressing issues that iPhone 6 and iPhone 6 Plus users encountered when updating to iOS 8.0.1, as well as several other improvements and bug fixes. The update is available for iPad 2 and newer models, iPhone 4s and newer models, as well as iPod touch 5th generation via an over-the-air update or directly through iTunes.
iOS 8.0.2 fixes a critical issue where iPhone 6 and iPhone 6 Plus users who updated to iOS 8.0.1 on Wednesday lost cellular signal and the ability to use Touch ID. It also addresses a HealthKit bug that prevented apps supporting the new APIs to function properly, as well as several other bugs.
