I'd recommend not jailbreaking your phone / ipod. It's about as cool and hip as using a hacked cablebox from 1989 that electrocutes you a little bit when you push the buttons. It offers about as much street cred as frosting and gelling your hair. Or almost as much a REALLY cool keychain that has a swear word on it. LOLOMGWTFBBQ! Reality check - "jailbreaking" your Ipod isn't cool. You're about as cool as the first American kid to realize they like anime.
im mentally retarded
