The game demos, and City ID.
To remove CityID you have to wait for the trial to be over, or you have to cancel the trial.
IF you open the app when the trial is over it'll ask to subscribe or to remove the app.
IF you open the app while the trial is active I believe you have a choice to stop the trial and then it'll ask if you want to remove the apps. I removed mine the day I got my D3 so I don't remember what it looked like.
