When i've jailbroken ipod's in the past i always failed with limera1n, i found using green poison alot easier

i first jailbroke mine with imera1n and it was the coolest thing then i found greenpoisen and it was just as good but beter.

Yes but I have had to jailbreak mine twice.. Apple Mobile Software stopped halfway of it jailbreaking so I restarted my iPod and just jailbroke again and all is good =D
