The iOS 11 software update arrives this week, which means anyone who fancies giving Apple's latest software a whirl can do so right now.
The days of the public beta are now behind us, because as of September 19 the final version of iOS 11 has been released by Apple.
However, and the reason for this article, iOS 11 won't be available on all iPhone and iPad devices. Older handsets and slates will be left in the lurch as Apple shifts to iOS 11 - so you may need to upgrade your hardware if you want the latest software.
So, without further ado, here are the devices the iOS 11 update will work on.
