I have a few questions, but first of all, here is what I am running. I have an iPod Touch 3rd Gen, v3.1.3 and it's already Jailbroken with Spirit. My computers OS is Windows 7 Ultimate (if that info is needed). Now come the questions: 1. I'd like to upgrade my iPod the 4.0 firmware but without losing my cracked Installous app and Cydia apps. How can I do this? 2. If I cannot do the above, is it possible to sync my cracked apps to iTunes, upgrade to 4.0, re-jailbreak and then re-sync my apps to my iPod. If so, how? 3. Is there even a Jailbreak for 4.0? If so, what is it? Thanks in advance and if anyone can help, I'll be eternally grateful.
