The Chronic Dev-Team has finally released the new version of Greenpois0n, which features a full untethered jailbreak for iOS 4.2.1. No SHSH blobs needed. The exploit used has already been patched in iOS 4.3, so it not work on future iOS 4.3.
You can jailbreak iPhone 4, iPhone 3GS, iPod Touch 2G, iPod Touch 3G, iPod Touch 4G, iPad. Unlike redsn0w 0.9.6 this is untethered, so there is no need to connect iOS device to a computer after restart.

Unlockers: do not update to stock iOS 4.2.1. You should keep your baseband version. Wait for new version of PwnageTool.

DevTeam worked hard for the last several hours and released jailbreak tool for iOS 4.2.1. It is redsn0w 0.9.6 b4.
As usual we remind all ultrasn0w unlockers please stay away from this official firmware. Wait for the ability to create custom 4.2.1 IPSWs that don’t update your baseband!
New redsn0w 0.9.6 b4 uses limera1n exploit and will successfully jailbreak all devices. The only problem is that it is a tethered jailbreak, which means you will have to plug it to a computer and rerun redsn0w on every reboot. This so called tethered or semi-tethered jailbreak. This condition applies to iPhone 3GS (new bootrom), iPhone 4, iPad, iPod touch 2G (MC model), iPod touch 3G and iPod touch 4G. Hackers are working hard to create untethered jailbreak for these devices. To use future untethered jailbreak you need to save SHSH keys for iOS 4.1 using TinyUmbrella utility or directly in Cydia.
Old devices like iPhone 3GS (old bootrom), iPhone 3G and iPod touch 2G (non-MC model) can be jailbroken-untethered right now using this latest version of RedSn0w.
Apple finally released iOS 4.2 for iPhone 3G/3GS/4, iPad, iPod Touch 2G/3G/4G and even Apple TV 2G. Lot's of new features, especially for iPad. Apple calls new firmware 4.2, however the version is actually 4.2.1. Here are the download links:
Next iPhone/iPod/iPad firmare iOS 4.2 is due out soon. What can we expect in terms of jailbreaking 4.2?
Limera1n exploit for 4.2 in most cases is a tethered jailbreak. That means if you have to reboot your device, it will show a "connect to itunes" logo until you run the jailbreak software again.
iPhone 3G - will run 4.2 untethered. Redsn0w will be updated.
iPhone 3GS - old bootrom will run 4.2 untethered if done via Pwnagetool while updating from 4.1. Otherwise it will be tethered.
iPhone 4 - tethered
iPod 2G - untethered.
iPod Touch 3G, iPod Touch 4G - tethered
iPad - tethered.
Tethered jailbreak isn’t that bad for iPads and iPods. But if something happens and your iphone reboots while you’re away from your computer, you cant use the device until you get home and run some tool on your computer again.
We suggest not updating until new expoit will be implemented in new utility.
The community is working on a solution to this to either make the jailbreak untethered or at least semi-tethered. Semi-tethered means the device will at least reboot, but unjailbroken while on the road until you return to your computer.
These are instructions on how to jailbreak your iPhone using PwnageTool 4.1.2 for Mac OS X. If you need unlock and you have not updated to iOS 4 you will be able to preserve baseband and unlock iPhone using ultrasn0w.
This guide will work for iPhone 4, iPhone 3GS, iPhone 3G, iPod Touch 3G, iPod Touch 4G, iPad and AppleTV. Just use the right firmware and select the right device (step four).
UPDATE: Please, consider reading our Jailbreak & Unlock FAQ, especially if you have questions or troubles.
Step One
Make a folder called "Pwnage" on the desktop. Now you need to download there PwnageTool 4.1.2 from here and iOS 4.1 firmware from here.
When downloading the IPSW file, it is best to download it with Firefox since Safari often auto extracts it!
Step Two
Double click to mount PwnageTool then drag the PwnageTool icon into the Pwnage folder.
The iPhone DevTeam has just released jailbreak utility PwnageTool 4.1 for Mac OS X.
PwnageTool allows you to restore to a custom IPSW file. The main advantage of PwnageTool is for unlockers. It gives the ability to keep current baseband and preserve ultrasn0w unlock. This is only for those, who have not updated to iOS 4.1 by themseleves.
You can also add whatever packages you want in the “Expert” mode of PwnageTool, if you wish to pre-install something from Cydia.
MuscleNerd, a hacker from DevTeam, recently published a screenshot of anticipated jailbreak utility PwnageTool 4.1. It will support iOS 4.1 and will be able to preserve old baseband for unlockers, who have not updated to iOS 4.1.
From the screenshot we can tell that PwnageTool 4.1 will support:
These are instructions on how to jailbreak your iPhone 3GS (all bootroms) or iPhone 4 using Limera1n for Mac OS X. Limera1n supports iOS 4.0, iOS 4.0.1, iOS 4.0.2 and iOS 4.1. Use the same steps to jailbreak iPod Touch 4G and iPod Touch 3G and even iPad. You can find the Windows version of this tutorial here.
