I somehow managed to squigle my way to firmware 1.1.3 and jailbreak it I don't even know how!! I spent like 12 hours trying to figure it out and I finally did it, i've been having some major problems, like downgrading, but I finally did it. Anyways, now I have firmware 1.1.3 and installer.app on my iphone, but I don't have any signal , is there any way I could restore my iphone to firmware 1.1.3 using itunes and keep installer.app on it?
