Apple stopped signing iOS 12.0.1 on Tuesday, a move that prevents all iPhone and iPad users from downgrading their firmware via iTunes to any version lower than iOS 12.1.
It’s been almost one full month since Apple publicly released iOS 12.1, signaling one of the Cupertino-based company’s longest firmware signing windows in recent memory; most windows only last for about two weeks.
Apple officially released iOS 12.1 to the public last week, and if history is anything to go by, then that means the Cupertino-based tech giant will soon close the gates for downgrades to iOS 12.0.1 via iTunes.
Apple generally closes the signing window for older firmware approximately 14 days after a new version is released, give or take a day. That said, if you’ve been thinking about downgrading back to iOS 12.0.1, then you should probably get a move on.
