The rivalry between TaiG and PP reached new heights today after iOS 8.4 was released to the public by Apple. The PP team quickly released a jailbreak tool for the new OS only hours after its official release. The TaIG team, who claims PP stole its code, then released their own iOS 8.4 jailbreak tool an hour or two after the first jailbreak was made available. Now iPad and iPhone owners have two options to choose from when jailbreaking their devices.
The TaiG team today released version 2.0.0 of the TaiG Jailbreak Tool for iOS 8.3. At the time of this post the Cydia Substrate has not been updated to support iOS 8.3, so you may want to wait until Jay Freeman (@saurik) announces that Cydia is ready to go before you jailbreak your device. The tool is also only available on Windows at this time, however, it is safe to assume that an OS X release is close behind.
