Earlier today, Chronic Dev Team member Joshua Hill (@p0sixninja) announced via twitter that they've released Greenpois0n, a jailbreak tool for the iPhone, iPod Touch and iPad running iOS 4.1. This falls behind their initial goal of pushing the jailbreak out on 10/10/10 at 10:10:10AM due to GeoHot releasing his Limera1n jailbreak first.

Previously based on the SHAtter exploit, Greenpois0n now uses the same bootrom USB exploit that GeoHot implemented in his own release late last week. They decided on using the same exploit as to not give Apple any heads up on how the SHAtter exploit was conducted, in order to ensure that Apple doesn't quickly patch both exploits in a future iOS update.

You can grab Greenpois0n via, but you may also want to visit their blog before attempting the jailbreak for more info and to make sure your iOS device is supported. As with the Limera1n exploit, this allows for jailbreaking the iPhone 4, iPhone 3GS, iPod Touch (3rd and 4th gen only) and the iPad. Additionally, they've announced that a future update will also include a jailbreak for the Apple TV (2010) and the 2nd generation iPod Touch.

Will you be jailbreaking your iOS device using Greenpois0n? Let us know in the comments!

UPDATED: Seems to be some launch day pains so you may want to hold off using greenpois0n until the initial bugs get worked out. Either way, if you want to talk about it or get help, head on over to our Jailbreak Forum.
