Apple unsigns iOS 13.2, hindering downgrades from iOS 13.2.2

Apple stopped signing iOS 13.2 Thursday evening, a move that inhibits iPhone, iPad, and iPod touch owners from downgrading their handset’s software from the latest iOS 13.2.2 release.

It’s common practice for the Cupertino-based tech company to unsign older software sometime after a newer gets released. Doing so facilitates (sometimes involuntary) software upgrades, which ensures that the majority of iOS device users take advantage of the latest new features, bug fixes, and security improvements.
