Evad3rs team has come up with iOS 7 untethered jailbreak. The tool, provided by the Evasi0n team, allows users to jailbreak all iOS devices running versions 7.0 to 7.0.4.
But According to users on Reddit, the Evasi0n jailbreak comes bundled with a Chinese cracked app store known as Taig in addition to the unofficial version of Cydia.Numerous members of the jailbreak community are crying foul about the inclusion. iOS hacker pod2g, one of the members of Evasi0n, states that they were not aware that Taig sold pirated apps.

So question is why they have come up with these pirated App Store , some people claims that evad3rs were paid $1 Million just to include these App Store , these sounds correct as they have released an early version of jailbreak without much fixes and using old ios 6 style cydia. Hacker pod2g responds to this issue and that he was not aware of piracy, he said team will come up with an explanation on a thread on Reddit. So stay tuned till then.
But beware before Jailbreak, it may contain malicious code, we will let us know as we get more details.
