and can it be modded if its cod4 downloaded from the psn store?

Yes, you need a jailbroken PS3 to host lobbies, and it will work the same if it's from the PSN Store.

what about getting mods into dpad for example "press up for godmode" or stuff like that, basically binds. do ialso need jailbroken ps3 for that?
