TaiG releases, then pulls its 2.2.1 update for jailbreaking iOS 8.4
Here’s saurik’s comment on the release:
OK, so this is a pretty serious issue: the new patch that TaiG built just doesn’t work :/. I wish they would calm down and let me do this correctly. I’ve pulled their update.
Needless to say, the package was pulled from Cydia, and no longer shows up on TaiG’s website as well. I’m sure they are working on fixing whatever issues saurik spotted with the update.
