I know you guys are sick of hearing questions like this, but I can't find a straight answer. I'm currently jailbroken on windows using quickpwn 2.0.1 firmware file and 2.0.2 firmware on the phone. Everything is fine. All I want to know is if I need to do a restore as new phone before I can jailbreak to 2.1? Or if I will be able to just jailbreak leaving my phone exactly as it is now?
