I'm using an iPod Touch 4g with 4.2.1 firmware. I'm using greenpois0n RC6 (Which I've used on two other iPods and it has worked fine). I'm running Windows XP SP3.
I've tried everything, I've put it into compatibility mode, I've restored to factory default 4.2.1, and everything else I could possibly find on the internet, to no avail. When I run greenpois0n I follow all the steps perfectly, and it just makes me wait a few minutes then it says jailbreak failed.
At this point, I wouldn't even mind using another jailbreak (as long as it is untethered and for 4.2.1)
