Two days earlier we saw the release of GreenPois0n for Mac, and today we are presented with the Windows version. This is an untethered jailbreak for iOs 4.2.1

As usual there might be some hiccups but you'll find plenty of discussion in this thread. Remember, anyone looking to unlock should NOT be updating their baseband. Do not be doing any updating unless you absolutely have to.

The Mac version has also been updated and fixes many bugs and issues that people were having earlier. Check it out if your on a Mac and still having problems.

Go get the Greenpois0n untethered 4.2.1 jailbreak now!
