so i jailbroke a fresh ps3 with 3.41 i use my ipod nano 1g and hermes v4. i cannot sign in or up for psn network account because it says i need a system update. im completly new to ps3 moddage, however i am adept with this sort of stuff in general, couple questions. is it possible to downgrade a ps3? is there a way to activate my already made psn account? (i have one i used to use with my psp) im using gaia manager? should i be using something else? can i play online with my current setup? if not what do i have to do to play online? i know how to install pkg's i know how to ftp into my ps3, i know how and where to put games, and i know how to jailbreak is there anything difinitive i need to know that i dont? mainly my problem is psn network, i want to be able to chat and stuff with my ps3 friends.
