hey i have a 3g iphone with a 2.0.1 firmware and its jailbroken by winpwn 2.0.0.4

should I re-jailbreak it with quickpwn or restore then jailbreak it with quickpwn? is quickpwn even better or is it the same as winpwn?

QuickPWN is just a basic jailbreak and is the same... WinPWN does the same thing just gives you control over the jailbreak like if you want or dont want Installer, Cydia, custom boot/restore logos, partition resizing...
So just wait WinPWN 2.5 will be out real soon and then you can jailbreak with the new firmware...
