The big news int he iPhone world today is the launch of iOS 16.2, but users of older phones have an important reason to update as well. Apple has released iOS 15.7.2 and iPadOS 15.7.2 for devices that aren’t on iOS 16, most notably the iPhone 6s and 7, iPad mini 4 and iPad Air 2. It’s also available for newer iPhones that haven’t made the leap to iOS 16 yet.
To update your iPhone, head over to the Settings app and tap General, then Software Update. Then tap Download and Install and follow the prompts.
The update doesn’t include any new features, but it does contain bug fixes and numerous important security updates, several of which allow for arbitrary code execution and at least one of which that may have been actively exploited.
