If you don't want to bang down 13 bucks for the full-fat Chinatown Wars iPhone app, this free "Lite" version is worth checking out. It provides a good taste of the Nintendo DS game, with the first three missions playable.
The $13 version offers all levels, plus the minigames, and while the controls are a little bit awkward it's still a heck of a lot better than playing Solitaire for the umpteenth time. Bet you anything that a good percentage of the downloaders of the free version end up being up-sold to the full $13 game. Three levels is just not enough stealin' and dealin'. [iTunes via AppShopper]
