Apple's latest iPhone could mean good business for iPorn. The smartphone features a new video chat feature called FaceTime. The adult entertainment industry sees big potential in X-rated personal chats. In at least five cities, there are Craigslist ads seeking models specifically for video sex chats on FaceTime. Some ads even offer a free iPhone 4 for the models. Embracing new technology is nothing new for the porn industry. X-rated home videos helped to popularize the VCR in the 1970s. And Internet porn peddlers were among the first to use streaming video.
