Avid iOS jailbreakers are in for some great news, as the highly-anticipated TaiG 2.1.0 untether jailbreak update has appeared online with fixes for the Cydia Substrate issue on devices jailbroken on iOS 8.3.

This is really surprising, considering the fact that it has been just two days following the release of TaiG 2.0 untethered jailbreak for iOS 8.3, and the jailbreak community has already found the fix.
