I think that he's asking about internet radio...I doubt it, since A. WiFi and AM/FM Radios use different frequencies, and B. it would need a built-in Radio tuner.
If you have jailbroken your iPod (and who hasn't!), then you can get iRadio and its an app you install on your iPod and can tune into a bazillion streaming radio stations.
I highly recommend Radio Paradise - http://www.radioparadise.com/
