So iv'e been reading and some sites say you can update in itunes then install newest jailbreak? Some say you have to find the firmware first?? I'm currently on 4.3.1 on iphone 4. I just did my first jailbreak a couple weeks ago with redsn0w. It was pretty smooth and I'm scared to mess it up, updating so.. any tips and tricks would be greatly appreciated!! Thank you as always!
