Apple has released iOS 7.0.3, which adds iCloud Keychain and a Password Generator for Safari. The update features a number of bug fixes and tweaks, including an iMessage fix, the resolving of an accelerometer calibration issue, and a lock screen update that delays the display of “slide to unlock” when using Touch ID.
The update is available over the air through the Software Update screen in the iOS Settings app or via the iTunes software update process.
