That means that the iOS 8.4 and its subsequent iOS 8.4 jailbreak would have a lifespan covering the entire summer.
But it seems that the jailbreak development teams, particularly Taig, have found a way to make sure that the iOS 8.3 jailbreak tweaks and apps will still be compatible with the iOS 8.4 and so are the tweaks and apps for the iOS 8.4 jailbreak so the iOS 8.3 jailbreak still materialized.
Apple is now giving users more reasons not to jailbreak their iOS devices since its newest mobile operating system, the iOS 9 already includes new features that were taken from jailbreak tweaks.
Some of the cool new features of the iOS 9 have actually been around for a while in the form of jailbreak tweaks including proactivity, picture-in-picture video, low-power mode, among others, which jailbroken iOS 8 devices are already showcasing.
Upon the release of the iOS 9, the next question for users of jailbroken iOS 8.3 or iOS 8.4 devices is whether their jailbreak tweaks and apps will support the latest mobile OS from Apple. They could sure trust the jailbreak developer teams to give them the answer immediately after the official release of the iOS 9.
