Here's a blog from a friend of mine who has written an application for the iPhone. The application allows you to grab the image of a soduku puzzle using the onboard camera, the software then identifies the grid, the numbers that it contains, and then provides the answers! There is a video on youTube showing the application in action. You will find it here.You can buy the application via the Apple store and Chris has kindly published his sales data on the blog. It will be interesting to see how this develops. Good luck, Chris.
