Apple has made available iOS 8.0.2, an update that Apple says fixes an issue in iOS 8.0.1 that impacted cellular network connectivity and Touch ID on the iPhone 6 and 6 Plus. In addition to resolving the cellular connectivity issue, the update also repairs a number of other issues.
For example, it fixes a bug so HealthKit apps can now be made available in the App Store. It also: addresses an issue where third party keyboards could become deselected when a user enters their passcode; fixes an issue that prevented some apps from accessing photos from the Photo Library; improves the reliability of the Reachability feature on the iPhone 6 and 6 Plus; fixes an issue that could cause unexpected cellular data usage when receiving SMS/MMS messages; fixes an issue where ringtones were sometimes not restored from iCloud backups; and fixes a bug that prevented uploading photos and videos from Safari.
iOS 8.0.2 is free to download and install over the air, or via iTunes.
