  • Greenpois0n For Windows Released: Untethered Jailbreak for 4.2.1

    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!

      I'll do what I did for people with the mac version and post the iH8sn0w mirror a couple of times so that people will get the version down a little bit easier:


      Don't forget to run the program as administrator.

      Never mind. The question was answered while I was busy typing it. Thanks!

      Worked great over tethered redsn0w JB. Did not even have to restore to 4.2.1. If it gets stuck with all the lines of code on the screen, just re-run GP and it will work. You will see the GP skull replace the Apple logo. Awesome.

      Thanks CDT

      Has anyone done it yet? I'd like to know if Cydia installs fast, or is it having problems just like when the Mac version got released.

      Everything went perfect on mine. Cydia even loaded in less than a minute.

      Not required, but you should still back up your 4.2.1 SHSH if you havent already.
