How to Jailbreak 4.2.1 iPhone, iPod Touch & iPad Untethered! (Tutorial by Deltron)
Notes:
- This will work for any device and for every model from Apple on the 4.2.1 firmware (including the iPod Touch, iPad, iPhone)
- I recommend that you restore to the 4.2.1 firmware before jailbreaking. (Click here for a list of firmwares for your device.)
- This jailbreak is untethered (meaning that you are able to turn your device off and on without affecting the jailbreak).
- This is NOT an unlock.
- This is currently for Mac only, I will update this once Greepois0n comes out for Windows. VIEW BOTTOM OF POST FOR WINDOWS.

5. In DiskAid click on “Root Folder” to the far left and then click on the “tmp” folder in the first box. Drag and drop the three files from the “tmp” folder in the “fixed_loader” folder you opened earlier into the “tmp” folder on DiskAid, which should be the middle box in the app.
6. Next navigate to the “Applications” folder in DiskAid which is also located in the “Root Folder”. Find the Loader.app file and click on it to open it up.
7. Drag and drop the file called “loader” from the “fixed_loader” folder into the box all the way to the right. It will ask if you want to overwrite the file, do it.
8. Open the Loader app, tap to install Cydia.
9. Enjoy your jailbroken device by Deltron!
