Following the release of iOS 12.1.3 on January 22, Apple has stopped signing iOS 12.1.1 and iOS 12.1.2 the previous versions of iOS that were available to consumers.
iPhone, iPad, and iPod touch owners who have upgraded to iOS 12.1.3 will no longer be able to downgrade to iOS 12.1.1 or iOS 12.1.2.
iOS 12.1.3, available for all iOS devices able to run iOS 12, was a minor bug fix update that addressed issues with the HomePod, iPad Pro, CarPlay, Messages, and more.
Apple routinely stops...
As it does with every new iOS release, Apple on Tuesday stopped signing legacy iOS 12.1.2 code in a bid to ensure iPhone, iPad and iPod touch owners are running the latest version of the operating system.
Apple has pushed out its second round of developer betas to those enrolled in the company's test program, with new second betas of iOS 12.2, macOS Mojave 14.14.4, tvOS 12.2, and watchOS 5.2 now available to download.
