AdSense definitely shows up on my iPhone. It showed up on one of my Blackberries but not the other one. I believe it shows up on Android, but I don't have one.
Currently I use a plugin that serves up mobile pages based on the user agent, and that uses Adsense for Mobile. I'll probably still use it for some user agents even after I get the Responsive Design frame built.
