ok I already jailbroke my ipod touch when i was on firmware 3.1.3 using program "spirit" but then I updated it in iTunes to iOS4. so when I accessed my iPod the following programs were deleted "cydia,rock,installous etc. Also my theme I had before I updated was gone. So basically I want to jailbreak my ipod touch again by downgrading to 3.1.3 and jailbreak it with spirit or just find a way to jailbreak it without having to downgrade to 3.1.3. And I don't know how to downgrade and can't find a way to jailbreak it without downgrading ( I am currently :iPod Touch 3 gen. with iOS4 firmware MC Model) Someone Please Help
