5 Make Sure Your Device Is Compatible
Before getting excited about the new features and capabilities in iOS 11.3, you’ll need to figure out whether or not your iOS device will be compatible. Luckily, this is pretty easy to figure out. Basically, iOS 11.3 will be available on all devices that can run iOS 11.
So if you’re on any version of iOS 11, you should be okay. If you’re still using iOS 10, keep in mind that there are several devices that won’t be able to run the new update — namely older devices such as the iPhone 5, iPhone 5c and iPad 4 and older.
