    Ok, for those of you that are trying to use Greenpois0n to jailbreak 4.2.1 and getting the "Failed" error, here's what I did and it worked. NOTE: The steps below assume that is on your Desktop.

    1. Make sure you're using Greenpois0n RC5_2
    2. Make sure device is connected to your Mac
    3. Open Terminal
    4. Type "cd Desktop" without quotes and hit enter
    5. Type "open" without quotes and hit enter. A second Terminal window will open and Greenpois0n will start
    6. Follow the instructions in Greenpois0n to enter DFU mode and it will jailbreak
    7. Once jailbroken, a green "Loader" will be added to your device. This is supposed to allow you to install Cydia, but mine would not. If yours is the same, go to step 8
    8. Turn off your device
    9. Open Redsn0w 0.9.7b6
    10. Make sure the only option checked is "Install Cydia"
    11. Follow the instructions in Redsnow
    12. Voila! Cydia is installed, and you have an untethered 4.2.1 jailbroken device!

    Thank you SO MUCH for this post. Was pulling out my hair all day trying to jailbreak my iPad and your instructions worked fist time. Even had to re-install Cydia as suggested.

    Does this also unlock the phone to use with any carrier or do I have to install redsn0w to do that?

    I am following your instructions and after step 5 am getting a message that says Greenpois0n unexpectedly quit.

    When I click on reports it says:

    Incompatible library version: greenpois0n requires version 6.0.0 or later, but libcurl.4.dylib provides version 5.0.0

    Any ideas? I am running 10.5.8

    Also, not sure if this will help anybody:

    You have to be connected to the internet to run greenpois0n!

    I had completely disconnected from my network because I wanted to upgrade my iPhone 4 while preserving the 01.59.00 baseband and was paranoid. greenpois0n failed a bunch of times before I realized what was going on.

    The normal GP process and then steps 8 onwards worked for my iPad, many thanks.

    Navigate to /usr/bin/ and delete "animate." The skull will be gone.

    Delete Loader?


    Once Cydia has been installed, can I manually delete "Loader" app from my phone?

    Yes. Just open the app, hit the "options" button, hit, "uninstall loader" and close the app. Your device will reboot and it'll be gone.

    It does not unlock the phone. In fact, if you've upgraded to stock 4.2.1, then you've lost your unlock capability, since the new baseband is currently not unlockable. There is a way to install an unlockable baseband using redsn0w, but if you do it, you won't be able to ever install a stock firmware again, or restore to factory default.

    You rule! Worked like a charm after not working the regular way on iPad tethered 4.2.1.

    Strange question perhaps, but why does this work?

    This. I'm using my iPhone tethered to my laptop for internet and I think this is the reason why i keep getting jailbreak failed errors. I've tried it about 100 times (windows version, fyi)... and every time has failed, and i've tried everything that I can find to fix it and nothing.

    Does anyone have the cached payload files from a succesful iPhone 4 jailbreak using GP RC5 that I can use to test? They would be "iBSS.n90ap & kernelcache.release.n90"

    Anyone have these files that they could upload for me? Thanks :)

    Hello! I need a hand!

    I've done this Redsn0w method with a few iPod touches and iPhones! However, today I got my first 2nd Gen MC model. When I do all the same thing as I did with the other iPods and iPhones, Redsn0w simply doesn't let me do it, because it doesn't support MC models. I have no idea how to get Cydia onto it, as the Loader server is down!

    Any help would be very appreciated.
