Jailbreaking Any Ipod Touch, Iphone, or Ipad Version 4.2.1 Any Generation Using GreenPois0n

If you want to jailbreak your ipod touch, iphone, or ipad, then go to www.greenpois0n.com. Notice that the 2nd O is a zero. Then ( depending on which software you use ), download greenpois0n and save it to the desktop. You have to download either the windows version or the mac version.Go to http://download.cnet.com/WinRAR-32-bit/3000-2250_4-10007677.html ,and download winrar. You will need it extract greenpois0n out of the compressed folder. Once you are finished downloading winrar, double click greenpois0n. Winrar will apear. Then press "extract to" on the top. Extract greenpois0n to the desktop. Take your ipod ( or iphone, I don't care ) and plug it into the computer. Now you have to put your ipod into DFU mode. Now this step is very tricky. It was very hard for me because my ipod's power button was jammed. To put your iphone into DFU mode, you have to hold your ipod's power button ( top right for ipods, and top left for iphones and ipads ) and home button ( the bottom middle button ) together for 10 seconds. Then let go of the power button, still holding on to the home button, for 15 - 20 seconds. The screen be black and there will be no signal that it is in DFU mode so you have to count very carefully. If you hold it to long, it will go into recovery mode. You will know you are in recovery mode because it will show the Itunes logo and a wire connecting to it, or something like that. To get OUT of recovery mode, hold the power button until the screen goes black. Then plug it into the computer. Remember, you want to go into DFU mode, NOT recovery mode. If you don't get how to go into DFU mode, go search on Youtube or google. Once you have gone into DFU mode, open greenpois0n. If you have windows, it will say Prepare to jailbreak (DFU). If you have mac, it will say Jailbreak. Press that button. It will automatically jailbreak because you already put it into DFU mode. If your ipod screen goes white, don't freak out. It's a good thing. The second stage of the jailbreak is the override stage. Your screen will go black and you'll see text going down the page. This stage will take about a minute or two. Maybe shorter. When it is done jailbreaking, it will automatically reboot (restart). When it is turned on again, turn to the second page on your ipod. You will see an app called loader. Now make sure you have internet connection. Not 3G. If you use 3G, downloading Cydia will be very slow. When it is done, it will automatically reboot after, well, a few seconds. Then Cydia will show up on your Ipod. Then your done!
