Greenpois0n Brings Long-Awaited Untethered Jailbreak To iOS 4.2.1

It's taken some time to get here, but the Chronic Dev Team has finally released an untethered jailbreak for iOS 4.2.1 devices. Early jailbreakers are claiming the installation can be a little finicky, but it'll still do the trick.

This latest version of Greenpois0n is available now for Mac OS X, Windows and Linux.

    Probably best to stay away from this one for now if a majority of users are having problems with it. Also, phone unlockers - don't bother.

      Worked a charm for me, though it did take a couple of attempts. Te biggest problem is the wait required to get the cydia store installed.

    Actually, works very well.

    But you need to install cydia via redsn0w, as too many people are jailbreaking and loader greenpois0n's loader app times out.

    Important thing to do is follow the instructions - exactly.
