After spending nights this past weekend trying to unlock and jailbreak my 1.1.2 OTB iPhone to 1.1.3, I've finally found THE BEST solution for Windows. Go download ZiPhone. Here's the link: http://zibree.blogspot.com/ I started the jailbreak process before taking a shower, I come out and the phone is jailbroken to 1.1.3! I'm gonna unlock it later after I get out of work. This was too easy.
