One of the amazing things about the iPhone is the number of niche applications. If you or your children play soccer, you'll want to try SoccerCard SKS, a customizable stats application for iPhone and iPod touch that enables you to create an unlimited number of virtual soccer cards featuring current player photos and season records, stats, and totals in real time. And you can e-mail these virtual SoccerCards to others. The app looks like a real SoccerCard, with a photo on the front. Rotating your phone 90 degrees brings up the stats, season record, and season totals on the back of the card. The app is $2.99.
