well what you just said was kinda confusing but if you only have one system on 3.72 then theres no way to get infections such as uav, 9th prestige, superjump, etc... unless you can get them from someone else who makes them.
so if i make them and i give the infected map to my friend then he can give it to his friend and his friend can give it to his friend etc... until you get it.
But if you want to make them then you must add the infection into your modded patch, which in turn must be data transfered from a jailbroken ps3 to your normal one.
