How do I know if my iPhone has been previously pwned?
I searched the forums and other websites already and unless I missed it, I couldn't find anything.
I'm trying to upgrade my already jailbroken and unlocked 3.0.1 3Gs to a 3.1.3 using a custom firmware but many tutorials say that my iPhone needs to be pwned before I can install custom firmwares. How do I find out of my phone has been pwned before? And if it isn't how do i pwn my phone for windows? A response would be nice, thanks.
