Apple appears to have stopped signing iOS 12.1.3 on Monday, a move on the Cupertino-based company’s part that prevents iOS device users from downgrading their device’s installed firmware from iOS 12.1.4 via iTunes.

This move doesn’t impact the jailbreak community very much because the latest jailbreakable firmware at the time of this writing is iOS 12.1.2, which Apple stopped signing more than a month ago. That said, the jailbreak community isn’t particularly rushing to downgrade to iOS 12.1.3 these days.

iOS 12.1.4 was released on February 7th to address a substantial FaceTime bug that enabled the caller to eavesdrop on the recipient under certain circumstances. Apple has since disabled the impacted feature on impacted software versions, only permitting devices that run iOS 12.1.4 to take advantage of the feature.

Apple frequently stops signing older versions of iOS to facilitate software upgrades among its user base. Doing so ensures that users are taking advantage of iOS’ latest and greatest features, protected by the latest security patches, and enjoying the latest performance improvements and bug fixes.

As always, you can track which versions of iOS are being signed for your device from the ever-so-useful IPSW.me website. You can also download relevant firmware files from the downloads page on iDownloadBlog.
