Chinese Developers Pangu and TaiG are not able to penetrate the tight security of the iOS so the iOS 8.2 Jailbreak and the iOS 8.3 Jailbreak release is in jeopardy while the iOS 8.4 release is expected at the World Wide Developers Conference (WWDC).
Apparently the security of iOS 8.2 and 8.3 is so advanced that TaiG and Pangu are not able to crack it. They are waiting for the next software update and hoping for a few security glitches so that they can sneak it.
However, their wait may be in vain because according to 9 to 5 Mac, Apple is developing a new security feature at the Kernel level. This feature is known as "Rootless" and it may make jailbreaking almost impossible.
Rootless is said to be a big feature in the iOS as well as the OS X. It will restrict even the administrative-level users from accessing some highly protected files in the Apple OS. It is highly developed to enhance the safety of the extensions, prevent the entry of malware and viruses. It will also preserve the integrity of highly sensitive data on the Apple device in a guarded way in order to prevent jailbreaking.
Apple iOS 8.4 is expected to launch at the WWDC, which is going to be held from June 8 to 12 in San Francisco. Apple acquired "Beats" for $3 billion and it is expected to be the hero of the next OS installment. iOS 9 is also going to be launched at WWDC, according to Gospel Herald. The audiobook service CarPlay will be an important feature of the iOS 8.4 version as well.
