Apple has released iOS 16.3, and the new iPhone update has been worth waiting for. As well as adding several brilliant new features, iOS 16.3 also fixes 13 security vulnerabilities, some of which are serious.
Alongside iOS 16.3, Apple also released the latest update to its iOS 15 operating system, iOS 15.7.3. The iOS 15.7.3 update fixes five security issues in the older version of Apple’s operating system, so which iPhone update should you choose?
The case for iOS 16.3
The iOS 16.3 update has been a long time coming, especially for those who care about security. That’s because the new iPhone update comes with the ability to use security keys to protect your Apple ID—a great new feature that everyone should be using, in my opinion.
In case you are wondering, security keys are a piece of physical hardware that you can use as an extra layer of protection to log into your iPhone. An example is the Yubico YuibKey.
From iOS 16.3, you can add security keys in your settings. Simply go to Settings > Apple ID > Password and Security and Scroll Down to Add Security Keys.
The iOS 16.3 update also comes with Advanced Data Protection, which sees the “gold standard” of security, end-to-end encryption added to more data in iCloud. In iOS 16.3, this has rolled out globally, having initially only been available to US-based Apple users.
But that’s not all—iOS 16.3 patches some major iPhone security holes, including three in WebKit, the engine that underpins the Safari browser, and another three in the Kernel at the heart of your iPhone.
At the same time, iOS 16.3 fixes several bugs and doesn’t appear to have added any major new ones, making it a good idea to update to the latest iOS version as soon as you can, if your iPhone can run it.
The upgrade is available for the iPhone 8 and later, iPad Pro (all models), iPad Air 3rd generation and later, iPad 5th generation and later, and iPad mini 5th generation and later.
The case for iOS 15.7.3
There really is only one reason to choose iOS 15.7.3 over iOS 16.3: if you have a device that won’t run Apple’s latest operating system. Until recently, the iPhone maker had been updating iOS 15 alongside iOS 16 for users of all phones, but from December when iOS 15.7.2 came out, this was no longer the case.
In other words, iOS 15.7.3 is for older iPhones that can’t run iOS 16. The update is available for the iPhone 6s (all models), iPhone 7 (all models), iPhone SE (1st generation), iPad Air 2, iPad mini (4th generation), and iPod touch (7th generation). If you have an older device, you should update to iOS 15.7.3 as soon as possible to protect it from security vulnerabilities.
If you have a newer device and you haven’t upgraded to iOS 16 yet, it’s probably time to take the plunge as it’s the only way to keep your iPhone secure.
iOS 16.3 or iOS 15.7.3—it’s a device-based decision
The decision between iOS 16.3 and iOS 15.7.3 depends on which device you use. If it’s a newer iPhone, please do update to iOS 16.3, especially if you’ve been avoiding upgrading from iOS 15.
For older iPhones, it’s important to update to iOS 15.7.3 straight away. Go to Settings > General > Software Update and upgrade to iOS 16.3 or iOS 15.7.3 to keep your iPhone safe.
