iOS 6 tethered jailbreak Available for iPhone 4 / 3GS [Tutorial]
The Apple iOS 6 has just been released yesterday to the latest Apple devices. However, that tiny amount of time was enough for those code-crunching experts to jailbreak the platform's latest release, albeit to a limited extent.
The iPhone Dev-Team's Redsn0w jailbreak works with iOS 6 on several devices, namely the iPhone 4, iPhone 3GS, and the fourth-gen iPod touch. Note that the jailbreak is tethered, meaning that the procedure has to be repeated each time your iDevice needs a reboot.
