iPhone app Police Scanner

Clarity and relevance are crucial to Police Scanner's users, as the acclaimed iPhone application allows listeners to listen to police, fire, and EMS activities around the world. Unlike other emergency scanner applications, Police Scanner's adaptive technology allows updates to data streams to post "live" within a few hours of changes made. Because emergency data streams can change so quickly, Police Scanner is able to provide the updated information to its customers without waiting for slow version changes released in the iTunes store.
With over 1850 national and international streams, Police Scanner offers the largest selection of police, fire, and emergency services streams available. Police Scanner is the only iPhone emergency scanner application to provide streams from eight countries. New streams are added daily.
Police Scanner runs on wireless LANs, the 3G network, or on the Edge network, and is compatible with both 2.x and 3.0 devices. Now with 50,000+ plus regular users, Police Scanner is the most far-reaching emergency stream application in the iTunes national and international stores.
