Jaillbreak iOS 4.2 On iPhone4.iPod Touch and iPad Using Pwnage Tool With Limera 1n (Untethered)

Earlier this day the famous iPhone hacker Muscle Nerd tweeted that iPhone Dev team have found a way by which they will be able to extend the current untethered jailbreaking tools to work on all A4 chips for the rest of life.People thought that once Apple has released iOS 4.2 the jailbreaking tools like Limera 1n and Green poison will be able pwn all devices which use A4 chips but with tethered jailbreaking however it seems that iPhone Dev team has found out a way to jailbreak untethered using Pwng tools and Limera 1 n etc.Many of you will probably be thinking that what is tethered or untethered jailbreaking.Tethered jailbreaking requires you to plug the jailbroken device into your pc every time you need to restart it whereas untethered jailbreaking doesnot require any such thing.
