Windows users rejoice! GreenPois0n has been released for Windows machines after seeing a few days of exclusivity for the Mac.

It was earlier today when we reported that the Windows version would make it to jailbreakers this weekend, and now the Chronic Dev Team has made good on its promises.

Check inside for the details and the download

As with the Mac version, the Windows version of GreenPois0n can be downloaded here, and will soon be available from our downloads section.

Again, there is a jailbreak specific forum here.

I've tried to jailbreak with greenpoison starting with my phone powered off and powered on and this isn't working. While I'm not a tech guru, I can't figure out if I'm doing something wrong here :P. I have an iphone 3G iOS 4.2.1 (8C148). After releasing the home button in the last step, how long should it take for something to happen?

Try waiting until you see the white text scrolling on black background on the iPhone before releasing the home button.

Edit: Alli posted a greenpois0n how-to on the main tipb site for Mac. It should be the same for windows.
