The iPhone is already shaking up the wireless industry. The video game industry may be next.
Following Apple's move to open the device to outside programmers, some of the top developers and publishers are already making games for it. The iPhone's high-tech hardware and Apple's plans to distribute software for it over iTunes give it a lot of potential as a game machine, they say.
In theory, developers could create games for the device that are more sophisticated than - while just as mobile as - those made for Sony's PlayStation Portable or Nintendo's DS, said John Carmack, president and technology director of Dallas-based idSoftware, which created the "Doom" and "Quake" franchises.
