Apple released iOS 15 to the general public a few months ago with a boatload of new forward-facing features. Moreover, it packed bug fixes and security patches that were not addressed in the previous iterations of iOS. If you have updated your iPhone to the latest iOS 15 or iOS 15.1 builds, you must know about the jailbreak status of the platform. iOS 15 or iOS 15.1 jailbreak is not available at the moment and there is a reason for it. Moreover, scroll down to check if you can still jailbreak your iPhone on older iOS builds.

Over the years, it has become cumbersome for developers to jailbreak their iPhones. If we look at the past, there is no jailbreak available for iOS 14 to iOS 14.8. This is one of the reasons why jailbreak developers tend to remain silent even if they have discovered an exploit that could lead to a potential jailbreak. If a jailbreak of a specific iOS 15 build is released, Apple would simply patch it in the next version of iOS. Henceforth, developers are hesitant to talk about an exploit and release of a tool for the initial versions of major iOS releases.
