iPhone 11, Switzerland, never been an Apple Developer, but had access to the iOS 17 betas.
Just went into updates and got this screen when clicking on "Beta Updates" (which was showing iOS 17).

Done a backup to iCloud; currently doing a backup to my laptop and then ....let's go! Let's see how my iPhone 11 copes with it.
