The Chronic Dev team has finally released a new version of greenpois0n allows you to jailbreak your iPod Touch on firmware iOS 4.2.1. The Chronic Dev team has made this jailbreak come with a major update, making the device you jailbreak an "untethered" jailbreak. For those people who don't know what untethered is, it means that your device will be completely fully jailbroken.

To download the jailbreaking tool you will need to visit Greenpois0ns website by clicking here. You can also visit Chronic Dev's developer blog to find updates and new things about Chronic Dev projects'. Those looking to get started should be aware, that Greenpois0n is only a jailbreaking tool and is not an unlocking tool, it supports Mac OS X, Linux and Windows PC but only works for the Apple devices listed below…

• iPhone 4
• iPhone 3G S
