Wondering how to Jailbreak iOS 4.1 with greenpois0n? Jailbreakers have a wealth of options when it comes to iOS 4.1. We’ve already looked at how to jailbreak via limera1n for Mac and how to jailbreak via PwnageTool 4.1 for Mac. Now we’re looking at the Mac version of greenpois0n. PC users shouldn’t have too much difficulty following along with any of these as the steps are generally the same. It’s really up to you what tool you decide to use. I suggest unlockers use PwnageTool 4.1 though, as it will preserve your baseband for future unlocking. And as always, we take no responsibility to any damage done to your iPhone, iPod touch, or iPad.
This version of greenpois0n will jailbreak the following devices:
iPhone 4 and iPhone 3GS
iPod Touch 4th and 3rd gen
iPad (iOS 3.2.2)
iPod Touch 2nd Gen

You’ll need to download greenpois0n first. After that you’ll be able to launch it and it’ll walk you through how to put your phone in DFU mode.
If for some reason it keeps failing, try making sure iTunes is running in the background. I know some people were saying it would fail unless iTunes was running. You’ll know it worked when iTunes starts telling you you’re phone must be restored before it can be used.
greenpois0n should then do its job of jailbreaking your phone. You’ll see a lot of random text across the screen of the phone and it’ll reboot itself. If all goes well, when it reboots, you should have a loader icon on your homescreen. (For some users it seems to be the greenpois0n icon, for others it’s showing up as a white blank icon.) Either way is fine.
Open the loader and install Cydia. Once that’s done, your iDevice will reboot once more and you should now have access to Cydia. Pretty simple process.
