Apple on Tuesday released iOS 8.1.3, a minor software release that brings several fixes to known problems and vulnerabilities, including one for the annoying storage problem that may prevent some users from upgrading. However, as MacRumors points out, the iOS 8.1.3 update also patches the security issues used by the iOS 8 TaiG jailbreak, meaning that users who want to keep their iPhones and iPads jailbroken should stay away from iOS 8.1.3 for the time being.

The TaiG jailbreak works on any iOS device running iOS 8.1.2 or earlier, including the iPhone 6 and iPhone 6 Plus.
While TaiG has not confirmed that iOS 8.1.3 breaks its jailbreak tool, unofficial reports from users have revealed that’s the case. Moreover, even Apple’s support documentation for the iOS 8.1.3 update credits TaiG for finding four vulnerabilities in the operating system.
The good news for those iOS users who have upgraded to iOS 8.1.3 already, but who also wish to keep the jailbreak intact, is that they can still go back to iOS 8.1.2 for a limited time, as long as Apple is still signing the previous iOS 8 version.
