Apple released urgent iOS updates, including iOS 12.5.8 for older iPhones, after emergency-call issues in Australia and a 2027 certificate deadline.

This update is compatible with all iPhones from 2019 on — that means the iPhone 11 onwards. The iPhone XS, XS Max and XR supported iOS 18 but aren’t compatible with the new software. Every phone from iPhone 11 to the latest, including second- and third-generation iPhone SE, right up to iPhone 17 series and iPhone Air, are covered.

Apple surprises users with unexpected update, quietly reviving older iPhones and iPads.

Alongside iOS 26.2.1, Apple today released an updated version of iOS 12 for devices that are still running that operating system update, eight years after the software was first released. iOS 12.5.8 is available for the iPhone 5s and the iPhone 6,

The last update, iOS 26.2, went on general release on Friday, Dec. 12. Exactly one month later, iOS 26.3 developer beta 2 was released. The next beta could be as soon as Monday, Jan. 19 — assuming the rumored iOS 26.2.1 release isn’t now taking place. That’s looking unlikely now. If it does appear, then I think iOS 26.3 will be later.

As iOS 26.2 arrives for many Apple iPhone users, here's everything to know about the latest update.

OS 12.5.8 extends the certificate required for iMessage, FaceTime, and device activation. With this update, all three keep working well after January 2027.

OS 26 features, which iPhones are compatible, latest version, problems, what's in iOS 26.2, and what's to come in iOS 26.3.

Apple just delivered a new software update to keep old iPhones working, a longevity flex most Android manufacturers still can't match.
