Okay PS3 users theres has been a new bypass method found for various games Like MW2 cod 4 and any other game that you want to mess about with without the patches. This allows you to play online also. There has been tonnes of Tuts about how to do a certain method were you keep signing in and out, but that worked like 30% of the time, this works all the time
