In this video, I'm going to show you how to jailbreak 4.2.1 Firmware for iPhone, iPad, and iPod Touch. It is untethered, and works on all device, all generations. It feels good to finally make this video.
Step 1: Download Greenpoison, Fixed Loader, Diskaid from Description.
Step 2: Update to Latest Version of iTunes.
Step 3: Make sure your device is hooked up to iTunes.
Step 4: Open Greenpois0n, follow on screen instructions to put device in DFU Mode. In the last step, let go of sleep but Keep Holding Home Button until you see scrolling Text at the end.
Step 5: Open Loader, if you see Cydia, click it and install. If you didn't see Cydia in Loader, like me, Open Diskaid.
Step 6: Drag the tmp directory files to the tmp directory on your device, as I did. Also drag the loader file to the loader application folder in your device, as I did. (Click Replace!)
Step 7: After doing so, reboot device and open Loader.
Step 8: Select Cydia, and install.
Step 9: Open Cydia, you are jailbroken.
The dev team is expected to update greenpois0n, so you don't need to go through the diskaid steps, but for now, if it doesn't work, doing the diskaid steps works. Enjoy your jailbreak! Don't forget to rate thumbs up and subscribe, and if you have any questions, leave your comments!
