Apple is releasing iOS 12 today (Monday, September 17). So if you own an iPhone you can download and install the latest version of iOS.
This video shows you how to update your iPhone so that it’s running iOS 12. It also shows a few ways in which iOS 12 is slightly different than iOS 11.
At first glance iOS 12 looks alarmingly identical to iOS 11. However, there are bound to have been small changes made under the hood you’ll notice over time.
Honestly, I do not understand anyone who gets excited by updates to iOS or Android. As long as your phone works, who cares what version of the operating system you’re using.
