Pocket god. Bought the iPhone last June and immediately bought pocket god. It's been on my device ever since
I know my first paid app was Brothers in Arms, followed 5 minutes later by Touchgrind. I was blown away that the iPhone could pull it off. For free apps, it was that cannon game by Discovery and Cube. Gotta miss the old days of the Appstore.
Game: Monkey Island App: Dont remember? Maybe Pocketmoney? Oh wait! I think SMule Ocarina... if you can consider that an app.
