currently there is no way in hell to play online with CFW, only way possible is to use zombiekillahs black ops mod and get online with that mod and play on the server with god mode and infinite ammo.
that is the 100% sure fire way to not get banned and sony wont even know your online
no need to swear like a dirty pirate, you asked and you got answers . Next time try actually searching on google with your question or in the forums seach engine.
the method I just described really is flawless and you will grant you immunity to sony detecting you ;-)
