As you can tell by the title I need help with USB modding on PS3. I am a complete n00b with this so please be nice .lol.
Anyway it would be great if you guys could answer my questions:

1. I'm not jailbroken , can I still USB mod?
2. Are these mods able to work online? As in public matches?
3. Are there mods which prevent you from being banned?
4. If I were to get banned, would it be a console ban or temp account ban?
5.Any other risks I should know about?
6. Could you recommend any existing gamesaves?(Multiplayer) (Force host and Anti ban are mostly what im looking for but im sure there is some cool stuff out there).
7. How do i actually do it?(step by step).

That is it for now , cant think of anything else to add...

Oh and a massive THANKS in advance.

Side note : I realize there is a tool called Red Eye which I can use to edit my own saves. Ill prob try it out later but for now pre-made ones will be great.
