[dMacMan]

Below you will find a detailed tutorial on how to jaibreak your Apple iPhone 3GS & iPhone 4 on iOS 4.2.1. Thanks to the Chronic Dev Team for providing the UNTETHERED jailbreak tool GreenPois0n.



*****Warning, if your using an iPhone 4 carrier-unlock DO NOT update to original firmware*****

1) Download the GreenPois0n Jailbreak Tools here:

Mac OS X = Green Poision RC 6.1

WINDOWS = Green Poision RC 6.1


2) Make sure and update to the latest version of iTunes... (v10.1.2 at the time of this posting)

DOWNLOADiTunes v10.1.2 - (Mac OS X 10.5+)
DOWNLOADiTunes v10.1.2 - (WinXP/2003/Vista/7)

3) Restore your iDevice to iOS 4.2.1 original firmware (if you’ve never jailbroken before, or are already on iOS 4.2.1... skip this step.) & (NO, the 4.2.6 next to the Verizon iPhone lnk is not a mis-print.)

*** NOTE: Users having iDevices which are already jailbroken (Tethered) via Redsn0w - You can also try GreenPois0n without restoring to a fresh iOS 4.2.1 ***
