Hi, I have a 3gs and I'm on 4.0. I believe I have the old bootrom, because I could restart my phone without a computer (to use blackra1n) when I was on 3.1.2. I upgraded to 4.0 when it was released, but now I want to jailbreak my phone. What should I do? Can anyone lead me into the right direction Please Register or Log in to view images? thanks.
