Jailbreaking an Ipod doesn’t give you free games and apps. It simply removes restrictions preventing you from running software released by people unaffiliated with the Apple store. Once jailbroken you have nothing more than you had before. You must still get games and apps developed for the specific device. You now, simply, have the ability to use them once aquired.
This is a moot, however. Apps must be written specifically for a device. Ipod apps will not work here.
