How to Untethered Jailbreak iOS 4.2.1
[ Step 2 ]
Run it once you have it and connect your iPhone, iPod Touch or iPad… Hit the Jailbreak button…
[ Step 3 ]
You will be asked to put your device in DFU mode, follow the procedure on your screens.
[ Step 4 ]
Once GreenPois0n for Windows recognizes your DFU mode it will start the Untethered Jailbreak process. So just give it a minute and do not do anything here.
[ Step 5 ]
When its done your device should boot up and you’ll be able to see “Loader icon” on your homescreen.
[ Step 6 ]
Tap on Loader icon to open and from the list choose Install Cydia. That’s it you can now enjoy an Untethered Jailbreak on your iPhone 4, 3GS, iPT or iPad running iOS 4.2.1.
