I wonder if this is a thing the EU will think of next.

I think you are wrong. If you have an iPhone that will run iOS 17 but not iOS 18 you will have the option to update to iOS 17. iPhones can always be updated to the latest iOS version their device supports. Now if your iPhone supports iOs 18 but you chose not to stay on iOS 16 then yes, your only option will be to move to iOS 18

There ist not such a Phone. 8 (Plus) and X only support iOS 16. XS (Max) and XR support iOS 18.

iOS 17.7 was still a major update for my iPhone 14 Pro.
After updating, my computer running macOS Sonoma required a download from Apple servers to be able to access the device again just like my computers running high sierra, unbelievable. :rolleyes:

The day is coming when iOS 17 will no longer be available…..

Since there’s no IPSW for 17.7, what’s the easiest/best way to downgrade from iOS 18?
