Head-to-head tests show that models as old as the iPhone 6S run iOS 13 at least as fast as iOS 12, and some devices see a performance boost.

Apple has stopped signing iOS 12.4 following the release of iOS 12.4.1. That means that it’s no longer possible to downgrade again from the latest version of iOS if you’ve already upgraded.

iOS 12.4.1 fixed a security flaw which allowed an iOS jailbreak to be created for the first time in ages. It’s no wonder Apple doesn’t want you turning back!
