    Hey well, i had a IPod Touch 3G 3.1.3 firmware, and it was jailbroken with load's of cracked apps and stuff and i started having problems with the internet on it like it was saying it was connected but not letting me on the app store and stuff so i took it to the apple store near me and asked them what they think and they couldn't work it out and suggested to do a format, wiping everything of, so i was like ye ok fair enough and once they formated it they also updated it firmware 4.0 and now i'm like really confused about jailbreaking it i can't seem to work out how to i've looked on google but they all say Ipod Touch 2G and Iphone 3G, so i tried to downgrade from 4.0 to 3.1.3 but it kept failing and not sure why i kept doing it in recovery mode when you hold the home and power button and stuff and then shift and click recover blah blah and just kept failing so was hoping if anyone had any ideas how to jailbreak my ipod touch 3g 4.0 firmware please >.< I'd be very grateful.

    Thanks in advance.
