The Nintendo Wii isn't the one in town that'll be getting a
port of Phoenix Wright. Capcom Japan recently announced that the first Ace Attorney video game will be making its way over to the iPhone & iPod Touch. While it'll mostly remain faithful to the Game Boy Advance classic, the game will be modified to take full advantage of the iPhone's features.
No date or price point has been revealed yet. The game is also Japan-only for the time being. But the Capcom Mobile American branch is already looking into bringing an English version to Apple's App Store as well.
