There are two ways to update the iOS operating system that powers your iPhone. You can do it by connecting your iPhone to your computer, or wirelessly.

We’ll walk you through both methods below.  

But before we get started, it’s critical that you back up your iPhone. If you’ve not backed up your phone before, here’s a quick and easy guide. 

Done that? Good news. Let’s push on…
