Ok i am certain i'm askinh a really nooby question but if u look at my specs below my user i have a 2g jailbroken 3.1.2 and i have no experience with 3.1.3 nor The itouch 3g. My friend has an ituch 3g and wants me to jailbreak it but he wasnt for certain it was accomplishable and i have no idea either but from my knowledge its not? i just need some support to answer this question and if so how. I know 3.1.3 is jailbreakable but i didnt think it supported the Mc model and 3GS old new boot rom. Thanks for the help, i appreciate it.
