Jailbreak iOS 4.2.1/4.2 Firmware for iPhone 3G,3G S, 4, iPod Touch 2G, 3G, 4G, & iPad

This video will show you how to jailbreak the newest 4.2.1 firmware for all compatible devices.

-It is an untethered jailbreak for the iPhone 3G and iPod Touch 2G.
-It is a tethered jailbreak for: iPod Touch 3G, iPod Touch 4G, iPhone 3G S, iPhone 3G, and iPad.

WARNING: "The notion of a "tethered" jailbreak is pretty new to many people, so here's a quick rundown on what to expect:

If you're on an iPhone3G, old-bootrom iPhone3GS, or non-MC ipt2g, life is easy. redsn0w installed an untethered jailbreak and so nothing below applies.
"Tethered" does not mean you cannot boot at all without PC/Mac assistance. If you have not installed any tweaks that hook into important programs like SpringBoard or CommCenter, your device will actually boot. However, jailbreak programs like Cydia won't work (and Cydia may still have a white icon). Also, certain built-in apps that had to be moved by Cydia will fail (Safari being the most noticeable example).
If you've installed MobileSubstrate tweaks that hook into SpringBoard or other important programs, your boot will actually fail (you'll get stuck at the Apple logo). You need to use redsn0w to "Just boot tethered right now".
Remember, @comex and others are working on a way to untether the 4.2.1 jailbreak. Meanwhile, the above 3 points hopefully will make it all seem less confusing :)"

-Basically, this means that certain apps may actually boot your device without the need of a computer, but that many other apps, such as Cydia, will fail to load unless you reboot every time after using. In this case, you will need redsn0w to boot it up. (ONLY FOR TETHERED JAILBREAKS)-

An unlock for the iPhone 3G and 3G S should be coming out soon, but until then, don't update, for you will lose your existing unlock. For iPhone 4, the 4.2.1 unlock is not in sight yet, so make sure NOT to update.

When a fully untethered jailbreak for 4.2.1 is released for all devices, I will post a video link here- ___________

The software we are using is redsn0w. Get it here-

We will also need our firmware file. Get it here-

Just follow the procedure and your device should be jailbroken.

Note- If redsn0w says it is not working at the point of the actual jailbreak. close it, and switch off your device. Run redsn0w again, except change its compatibility to "WIndows XP Service Pack 2) and then Run as Administrator.
It should work now.
