Ok, I was just surfing the internet for a while (as usual) and then I got a new text and it was my friend telling me about a cool app. When I went to download it, the App store told me that my pass was wrong. I re-entered it until it told me to retrieve my pass via iTunes. I then left it for like 2 mins to get some chips and a coke (I though App Store purchase server was down or something) and when I came back it refused to take my lock passcode. Its not jailbroken and I got it thursday. When I rebooted, it was fine.
