I have an iPhone 3GS. I updated to 3.0.1 when it came out then i jailbroke it. Then I updated to 3.1 while it was jailbroken using the usual itunes way. Now I"m trying to re-jailbreak it. "PwnageTool will work for the iPhone 3GS assuming you have already Pwned it at 3.0 or 3.0.1 ". I didn't jailbreak it with PwnageTool at 3.0.1 though, I jailbroke at with redsn0w. So can I jailbreak? or is that only for people that used PwnageTool? I would just try it myself, but I don't have a mac, so i have to ask a friend.
