I have an iPhone 3gs (new bootrom) that i've already jailbroken. The thing is I jailbroke it back when I first got it when it was on iOS 3.1.2 and has never been upgraded. I would love to have it upgraded to at least iOS 4.0 so that I can download things from the app store again and use the new features. I just can't figure out for the life of me how to do it. Do I need to get rid of my current jailbreak first?? Do I update it on iTunes first and then download the new jailbreak?? Can someone please either direct me to or reply with some simple step by step instructions on how to do it?
