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 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.

Assuming you're enrolled in the Apple public beta program, you can now grab the public beta directly on your iPhone. Just go to Settings, tap on General and select Software Updates. On that screen, tap on Beta Updates to find the iOS 26 beta.
