The Chronic Dev-Team has released Greenpois0n, their utility for jailbreaking the iPhone, iPad, and iPod touch on iOS 4.1.

After much controversy, the tool has been updated to use the bootrom exploit found by Geohot.

Unfortunately, only a Windows version is currently available; however, a mac version and ipt2g support are coming soon.

You can download Greenpois0n from here.

Our tutorials will be posted shortly. Stay tuned!
