For those of you who don’t know, GreenPois0n is based on a low-level bootrom exploit which Apple won't be able to patch with a new iOS firmware; instead, they will have to introduce a new hardware for the current devices to close the lopphole. That means all existing 4th-generation devices now can be jailbroken forever thanks to GreenPois0n! We will be back with quick how-to guides soon, stay tuned for that !!
Donations keep Support ALive !!

UPDATE

Chronic Dev has just released the Mac OS X version of Greenpois0n to jailbreak iOS 4.1 on iPhone 4, iPhone 3GS, iPod touch 4G/3G and iOS 3.2.2 on iPad. Now I have just prepared the step by step Mac guide to jailbreak iOS 4.1 on iPhone 4/3G and iPod touch 4G/3G with Greenpois0n.

STEP 1: Download Greenpois0n jailbreak (link at the end)

STEP 2: Connect your iPhone/iPod to your computer via USB then launch Greenpois0n jailbreak application and hit "Jailbreak" button.

STEP 3: Follow the steps shown on the next screen shots to put your device in DFU mode.

• Now you have to press and hold the sleep button for 3 seconds.

• Continue holding sleep, then press and hold home for 10 seconds.

• Now release sleep button but keep holding home for 15 seconds.

STEP 4: Once your iPhone/iPod is in DFU mode, the jailbreak will begin.

STEP 5: Now press "Complete" button.

STEP 6: Restart your iPhone, now you will notice Loader application icon on your springboard, hit this icon.

STEP 7: Now press "Cydia", then "Install Cydia". After finishing you will be asked to remove Loader from your device, click "Remove", then press Home button, the device will restart automatically.

 

 

 

STEP 8: After your device restart you will find the Cydia icon, Congratulations.

Note: Since there is no way to unlock 05.14.02 / 2.10.04 basebands, you should upgrade to iOS 4.1 with preserving your baseband before using Greenpois0n jailbreak!
