We all got so excited when an untethered jailbreak for iOS 7 was finally released just before Christmas. Team Evad3rs came to the rescue again with their Evasi0n7 jailbreak for iOS 7 but now that all looks to be going sour as iOS 7.1 beta 4 is released and it looks like it partially patches the Evasi0n7 jailbreak. The third beta of iOS 7.1 didn't touch this jailbreak but it looks like Apple has begun patching the exploits with their fourth beta.
We did think that Apple might have been planning on waiting until the final beta befrore shattering our iOS 7.1 jailbreaking prospects, but the kernel exploit used by Evasi0n7, which allows the jailbreak to take place, has been patched according to a tweet by developer iH8sn0w. He followed this with a later tweet advising everyone that they shouldn't expect an Evasi0n7 update for iOS 7.1 beta 4+. He had initially pointed out that the userland exploits were not plugged with 7.1 beta 4, but with kernal exploits having been patched, it looks inevitable that no more jailbreaks will be released for betas. In fact, the only reason the third beta build was supported by Evasi0n was because Apple had basically left all the jailbreak gaps untouched.
It now looks like the jailbreak scene and particularly the Evad3rs team, will be regrouping and preparing themselves for the next big release of iOS before they consider making any major updates to the Evasi0n tool. Whether this will be for iOS 7.1 GM or not remains to be seen. MuscleNerd also stated that comments on beta exploits being plugged by Apple is something of a rarity, and it only helps Apple.
If you want to download the fourth beta of iOS 7.1, you will need to have a Developers account which will give you access to several other pre-release software for both iOS and Mac as well as associated Apple products. We will of course keep you updated on what is happening in the jailbreaking scene as soon as we hear anything.
