Have you updated your iPhone to iOS 7.1 beta 3 which was released yesterday ? Probably you should try this newly released unofficial modified version of Evasi0n7 which jailbreaks iOS 7.1 beta 3 only. Just after the release of iOS 7.1 beta 3, the first thing I did is trying to jailbreak my device using Evasi0n7 latest versions. I was quickly (and unsurprisingly I might add) met with an error message stating: Sorry, the version of iOS (11D5127c) of the attached device is not supported.
The first question you should ask me: “Is This unofficial version of Evasi0n7 can jailbreak my device running on iOS 7.1 beta 3?” After 15 minute from testing, I can state that the answer to that question is yes.
NOTE: We don’t recommend downloading this unofficial tool and everything you do will be at your own risk. At any rate, before doing anything, make sure to backup your device for safety.

Again, this modified version hasn’t been sanctioned by the Evad3rs and we cannot vouch for its safety. If in doubt, it may be wise not to use this tool.
