Untethered iOS 4.2.1 jailbreak now available to all systems

Fond of jailbreaking your iPod devices? Chronic Dev Team just released their untethered jailbreak for the latest iOS 4.2.1 firmware a couple of days ago. However, it was only today that they made greenpois0n RC5 available to Windows and Linux users. Head to greenpois0n website to download the tool.


The jailbreak is not as easy as Jailbreakme during the iOS 4 days but still, the instructions included in the tool are pretty straightforward. If you’re still hestitant, I documented how I jailbroke my iPad using greenpois0n along with some tips.

New iPod Touch owners will benefit here since it took a really long time for an untethered jailbreak available to the iOS 4.2.1. iPad users too who can now enjoy the benefit of iOS 4.2.1’s multitask and GameCenter support along with their Installous apps.
