The jailbreak community has long been waiting for the release of the next iOS 8 jailbreak, as Apple has patched up all used exploits in TaiG jailbreak with the release of iOS 8.1.3 update.
Stefan Essar aka i0n1c had recently showcased a jailbroken iPhone 6 Plus running on iOS 8.4, which adds more credence to the belief that the next iOS jailbreak is under works.
This belief is further strengthened by the fact that Apple has recently seeded the iOS 8.4 Beta to developers with its public release expected during the month of May or June.
Apple is already gearing up for the final public release of iOS 8.4 ahead of the iOS 9 launch scheduled for WorldWide Developer Conference (WWDC) in September.
This development clearly signals that the Apple developers would be busy in patching up all existing bugs in iOS 9 ahead of its release and hence will not find enough time for developing the ageing iOS 8 any further.
Team TaiG and other leading jailbreak developers are decidedly playing a waiting game for Apple to release iOS 8.4, as they run the risk of losing all known exploits if they released the iOS 8.3 jailbreak, ahead of the iOS 8.4 official launch.
Prospective jailbreakers are advised to hold back their temptation to upgrade to iOS 8.4 once it gets released, as it will kill any future jailbreak prospects while rendering all existing exploits useless.
It is still not clear if the TaiG team would release its final iOS 8 jailbreak for iOS 8.3 or iOS 8.4 iteration, as their decision would be based on Apple's strategy of patching up exploits in its forthcoming iOS 8 update.
