Apple on Thursday stopped signing iOS 12.1.4 for its mobile devices, a move on the Cupertino-based company’s part that prevents users from using iTunes to downgrade their firmware to any version below iOS 12.2.
Apple just released iOS 12.2 to the public last Monday, and so the decision to stop signing iOS 12.1.4 today is somewhat abrupt, even to Apple’s standards. The last time Apple stopped signing an older version of iOS, the window remained open for several weeks before Apple flipped their magical anti-downgrade switch.
