Unlike last year, several iPhone models won't be eligible to download the newest iOS when it makes its debut this fall. This trio of models first released in 2018 won't be coming to the iOS 26 party:

As part of iOS 26's interface changes, your iPhone lock screen can take on a new look with spatial photos available as the background image for your phone and an adaptive time feature that adjusts the look of the on-screen clock to fit with the other visual elements. We go through all the iOS 26 lock screen changes.

As well as a refreshed new look for system components like buttons and tabbars, the Liquid Glass redesign of iOS 26 also extends to app icons. For the first time since iOS 7, Apple has redrawn all of the system apps with new artwork. That means a whole new look is coming to your iPhone home screen this fall.
