p0sixninja is a very famous iOS Vulnerability researcher. Even though, he was absent from the “Dream Team” of Jailbreaking: Evad3rs!
Now, we all know that Apple has significantly increased the security of their Mobile OS, and just some small teams of Jailbreakers are researching for Security Holes.
So, P0sixninja leads a new Community, OpenJailbreak, which makes public the effort of Vulnerability Researching for everyone who is interested!
