Apple iOS 18.6.1 is compatible with all iPhones from 2018 on. That’s the iPhone XS, iPhone XS Plus and iPhone XR models and every phone since. That means the iPhone 11 series, iPhone 12, iPhone 13 and so on right up to the iPhone 16 series, plus the second- and third-generation iPhone SE models as well as the iPhone 16e.

Apple's iPhone 17 event is set to run on Tuesday, September 9. That means we should finally get the skinny on the presumed iPhone 17 lineup — including the ultra-thin iPhone 17 Air — in less than a week. (In the meantime, we have a breakdown of how you can watch the iPhone 17 launch .)
