Police Scanner for Windows Phone 7, developed by Carmelo Milian (developer of PhotoWiz), is dialed in and ready for release. The application taps into Police and other emergency service feeds from various cities in the U.S. and abroad.
Based on the demo video, locations range from Los Angeles, California to Memphis, Tennessee to Manitoba, Canada. The application browses for feeds, pick country, then state, then get all feeds (a little over 2,000). You also have a handy "Ten Code" reference to make it easy to interpret what "10-09" or "10-20" means.
Police Scanner is an interesting application that brings a new twist to Windows Phone 7. It will be nice to see this one in action.
