Fight night champion help?

Is there a way to download a cab off of the fight night champion ea site without psn? Because if so im tryin to find a way to put them in a save.

also has anyone try to unlock anything extra from on the disc like people did on mortal kombat and such.

That's what I want to know!!!!
You can use Rebug to use someone else's CAB save but if you go to another CFW your save will be useless.
