An iOS developer named Aaron (@iOShXr) has claimed that he has been able to jailbreak iOS 8.4 beta 4 using the newly released TaiG 2.0.0 tool. The official version of the tool is capable of jailbreaking iOS 8.1.3 up to iOS 8.3, however the developer says it took him about 5 minutes to reverse engineer and another 10 minutes to patch in support for iOS 8.4 b4 to it. If this is true then we might be able to get the iOS 8.4 jailbreak sooner than later, that is if Apple doesn’t close the exploit used by TaiG for the iOS 8.3 jailbreak in the final version of iOS 8.4.
To back his claim Aaron has also shared a screenshot of iOS 8.4 beta 4 with Cydia icon on the homescreen.
So why did TaiG team release the jailbreak early, potentially endangering the iOS 8.4 as Apple can still close the exploit used in TaiG 2.0? The answer according to Aaron is money, since if they had waited for the public release of iOS 8.4 Pangu would have beaten them to the release.
While we don’t mind the early release of the jailbreak, we really hope Apple doesn’t close the vulnerability in iOS 8.4 so we can install the latest version of the operating system on our devices and still be able to jailbreak it.
iOS hacker @i0n1c also weighed in saying if TaiG works on beta 4 then it might as well on the final version of 8.4.
Someone claims that a modified version of TaiG runs on iOS 8.4b4 -> if true then the jailbreak might just work on the final – 8.4.
