The Chronic Dev Team is currently working on a new project called “GreenPois0n” that will unlock and Jailbreak the iTouch 3G. Apparently the new device is still vulnerable and have already managed to crash the iBoot which is a good sign.
You can visit the address www.greenpois0n.com but when he found nothing but a link to the blog and one account on Twitter. The exploit that was found is in a position to crash the iBoot and continuing in this direction will be able to figure out how to circumvent the protection and enable the Jailbreak.
