Following the release of iOS 13.2.2 with a fix for the poor multitasking issues on iPhones, Apple has stopped signing iOS 13.2. This means it is no longer possible to downgrade back to that release of iOS 13.
iOS 13.2.2 is the latest public release of the OS, with Apple currently beta testing iOS 13.3 with some minor changes and enhancements. If your iPhone is still running iOS 13.2, you should upgrade it to iOS 13.2.2 due to just how broken multitasking is in iOS 13.2.
Most users usually tend to avoid updating to the latest release of iOS in hopes of a possible jailbreak. The good thing is that even if you upgrade your iPhone to iOS 13.2.2, you will be able to jailbreak it using checkra1n. The first public iOS 13 jailbreak tool supports iOS 13 – iOS 13.2.2 on all iPhones and iPads launched until the iPhone X. For newer iPhones like the iPhone XS and iPhone 11, no jailbreaking tool has been released yet so there’s no point in not upgrading to iOS 13.2.2.
