Apple today released iOS 7.0.6, a small but important update that fixes a single issue. Released less than a month after Apple released iOS 7.0.5, it fixes an issue with SSL connection verification. It is available for the iPhone 4 and more recent models up to the iPhone 5C and iPhone 5S as well as the iPad 2 up to the iPad Air.
A similar update, iOS 6.1.6 was also released for older devices such as the iPhone 3GS as it cannot run iOS 7.
To update, simply head over to Settings > General > Software Update. The update weighs in at just over 35MB.
The next major update to iOS is iOS 7.1. At last word, it could arrive perhaps as early as mid-March.
