And it will eventually ask you this question: "Do you have an iPhone contract that would activate normally through iTunes", answer it "No" you don't have the official carrier support - answer it "Yes" if you are supported with any carrier such as AT&T & your baseband will be updated to the latest version. Then, our PwnageTool will continue the process of creating the .ipsw file.
