Now that the latest version of Greenpois0n has been released to the iPhone jailbreaking masses, if you are having a bit of difficulty getting Greenpois0n untethered jailbreak for iPhone iOS 4.2.1 working, we have a quick tutorial video for you.
The Greenpois0n 4.2.1 Untethered Jailbreak How To video comes our way courtesy of YouTube user Mad33y1 and lasts almost one and a half minutes of going through the process of getting the Greenpois0n untethered jailbreak onto your iOS device.
Have to say though it’s basically just a written tutorial rather than actually showing the viewer the steps loading greenpois0n onto your device. However if you prefer a written tutorial then you can either check out the video below or hit up the iPhone Download Blog.
I again checked the Greenpois0n website and it still appears to be down, but if you have managed to grab the jailbreak which is currently only for Mac, and require a little help then jump on down and check out the tutorial video…enjoy.
