The untethered jailbreak hasn’t been released yet for the iOs 6. A fake untehtered jailbreak with a programm called RedPois0n is on internet. For the moment, there’s only a tethered jailbreak, but only for the A4 chips (iPhone 3GS, iPhone 4 and iPod Touch 4G).
You can see on the image they madeit written “By Chrnic Dev Team”. There’s the Chronic Dev Team and they work on the jailbreak, but no Chrnic Dev Team. They have also made a video to show that it works, but be careful, it doesn’t work!
The video has been removed from Dailymotion, that’s a good thing.
The download links of this programm ask you some informations about your Facebook acount, so there can be a lot of virus.
So wait for an official untethered jailbreak. For more informations you can follow me on Twitter (@DevSk0re) and follow Chpwn (@chpwn who is working on the jailbreak).
