Fellow jailbreakers, the fun is over. Apple has patched the vulnerabilities used by the Evad3rs team. iOS 6.1.3 comes with the fix for jailbreak.
This post is specifically written to warn you. If you have been using a jailbroken device and want to continue using it, STAY AWAY from iOS 6.1.3.
The fix by Apple didn’t came as a surprise as it was expected and already predicted by everyone in the jailbreak community. Apple always fix the jailbreak vulnerabilities as they have to protect the security of the operating system they are providing to the millions.
Evasi0n was the most famous jailbreaking software in the short history of jailbreaking, available for iOS 6.0 to iOS 6.1.2 and finally patched today in iOS 6.1.3.
The only exception are the old devices vulnerable to Limera1n exploit that includes iPhone 4 and iPod Touch 4G that will be able to use tethered jailbreak on iOS 6.1.3.
So if you are on a newer device and don’t want to lose jailbreak, you must stay away. Another very important thing is that if you have a newer device, you cannot downgrade back to iOS 6.1.2 once its updated to iOS 6.1.3 even if you have saved SHSHS blobs. So keep in mind, there is no coming back.
As pointed by MuscleNerd, Apple has credited the Evad3rs team for the 4 vulnerabilities they have fixed out of 6 which Evasi0n is using to inject Cydia.
Evasi0n was using multiple exploits to jailbreak iOS devices as earlier explained by PlanetBeing. Since the security of iOS has enhanced so much that it has become impossible to use one or two exploits to release the jailbreak. That is the same reason why lately we have seen the developers working in teams to combine their work to reach the final task.
More likely, the developers won’t be releasing any jailbreak for iOS 6.1.3 or for upcoming versions of iOS 6. Most probably, we will see the next jailbreak after the public version of iOS 7 releases in September this year. Till then, keep your device to iOS 6.1.2 if you want to keep enjoying the perks of jailbreak and Cydia.
It is obvious that iOS 7 jailbreak will be more complicated for developers than any of of jailbreak they have created so far. But we are hopeful as always.
