Due to some major changes in 3.0 xpwn (the program Jailbird depends on) does not play nice. I am trying to see if xpwn will be updated by the Dev-Team. More news to follow.

This is good news people.
Although for the numerous non believers out there, I am debating releasing a version of Jailbird that works with firmwares 2.0.0 to 2.2.1 until a new version of xpwn is released.

I’d like to hear some feedback on whether you would want this or wait until I can release a working 3.0.0 version.
