Both iPad and iPhone have applications that funnel Internet radio broadcasts to their users. The application finds local law enforcement radio traffic and beams it to the iPhone. A friendly citizen heard an officer give his cell phone number to another officer over the police radio. The citizen called the surprised officer on his cell to warn him that his cell phone number had just made public by the iPhone app. The application is called Emergency Radio and sells for $2.99. There is no privacy out there. Beware!
