The jailbreak tool for iPhone 5 and other iOS 6.1 devices was recently released by the team of hackers named evad3rs. In the tool, called evasi0n, the team essentially used some of the exploits present in iOS 6.1. In the latest beta release of its updated firmware, Apple seems to have patched at least some of these exploits.
The iOS 6.1.3 beta 2 release from Apple came last week. Among other enhancements that Apple had promised to include in it, the developers found out that the company had also attempted to patch a few exploits which may render the evasi0n jailbreak tool useless.
For now, the beta release is still available to developers only. But it is expected that it may soon be rolled out to the users within the next one month. Once that happens, all such devices which would be updated to the new version will no longer be able to jailbreak using evasi0n. However, those users who have already accomplished untethered jailbreak on their devices using the tool can avoid this by not updating to the new firmware release.
According to a notable member of the evad3rs team, David Wang, Apple had patched at least one of the five bugs that the evasi0n jailbreak exploits. However, if the team wants to help new iOS users accomplish jailbreak on their devices in the future, they may have to write a new jailbreak from scratch. The team says that it knows enough iOS bugs to be able to do so but that it may take some time.
So if you are one of the free souls who wants to accomplish jailbreak on your iOS device, be quick about it and use the evasi0n jailbreak tool before the new firmware rolls out. And for those who have already used the tool, don’t forget: never update to the new firmware.
