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 3GS, iPod Touch 2G, iPod Touch 3G, iPod Touch 4G, iPad and Apple TV 2G. Unlike redsn0w 0.9.6 this is untethered, so there is no need to connect iOS device to a computer after restart.
There is only Mac OS X version available. Chronic Dev-Team will release Windows and probably Linux version soon.
Unlockers: do not update to stock iOS 4.2.1. You should keep your baseband version. Wait for new version of PwnageTool.

UPDATE:
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.
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.
The Chronic Dev-Team has released RC4 of their Greenpois0n jailbreak utility which brings support for the iPod touch 2G.
Greenpois0n RC4 posted on www.greenpois0n.com – support for iPod Touch 2G, MC and MB, both untethered.
