Folks, great news for you! After Geohot’s dramatic session now Chronic Dev Team is in action and released GreenPoison. we just got a tweet from @p0sixninja:
Who is ready for GreenPois0n?
Now we also ask whose ready for the long awaited untethered Jailbreak called Greenpois0n.
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 loophole. That means all existing 4th-generation devices now can be jailbroken forever thanks to GreenPois0n!
This release of greenpois0n supports:
- – iPhone 4
- – iPhone 3G S
- – iPod touch (4th Generation)
- – iPod touch (3rd Generation)
- – iPad
Method is the same and easy all you have to do is put your device into DFU mode and Inject the Pois0n.
