Chronic Dev Team has finally released the much awaited GreenPois0n RC5 which brings full untethered iOS 4.2.1 jailbreak for all iOS devices. Unlike Redsn0w 0.9.7, GreenPois0n RC5 doesn’t require you to have SHSH blobs of 4.2b3 saved on Cydia. You can jailbreak any iOS device out of the box on iOS 4.2.1 using this latest version of GreenPois0n.

The following instructions will help you jailbreak iOS 4.2.1 on iPhone 4, 3GS, iPod touch 2G/3G/4G, iPad and Apple TV 2G using GreenPois0n.

NOTE: If your iPhone 4 rely on an unlock, do not update to iOS 4.2.1 yet as doing so will upgrade your baseband, making it impossible for now to unlock.

Step 1: Download GreenPois0n from the link given below.

Step 2: Connect your iPhone via USB to your computer and click on “Jailbreak”

Step 3: Now follow the following onscreen instructions to enter DFU mode:

* Press and hold the sleep button for 2 seconds
* Continue holding sleep; press and hold home for 10 seconds.
* Release sleep button; continue holding home for 15 seconds.

Step 4: GreenPois0n will now start “Jailbreaking” your iOS device untethered on 4.2.1

Step 5: Your iPhone, iPad or iPod touch should now be successfully jailbroken on iOS 4.2.1. Now start “Loader” found on the homescreen and install Cydia

This is it! You are done !

I just want to remind everyone that even though this Jailbreak has been release, please keep in mind that you will probably have more issues than it's worth upgrading to iOS 4.2 I strongly urge users to STAY on iOS 4.1 if you have NO PARTICULAR REASON to upgrade to iOS 4.2 There is really nothing great about iOS 4.2 and keep in mind that there are still quite a few 3rd party apps that haven't been updated to work with iOS 4.2 yet.

Also keep in mind that iOS 4.3 is right around the corner which IMO is gonna be a better choice of an upgrade than iOS 4.2 So if you are on iOS 4.1 I would highly recommend holding out until iOS 4.3 comes out and wait to see how everything pans out. No sense wasting your time updating your device only to have to do it again in a couple weeks.

Also you guys who need your devices UNLOCKED, keep in mind that iOS 4.2 REQUIRES A BASEBAND UPDATE TO WORK! Meaning that you will be forced to update your baseband in order to use iOS 4.2 and there is still NO UNLOCK for the most current baseband!

DON'T BE DUMB AND UPGRADE JUST TO UPGRADE! You are gonna end up causing yourself more of a hassle than it's worth. You might gain a few silly little features in iOS 4.2 but think about what you will possibly lose with incompatible 3rd Party Cydia Apps!
