streaming public and emergency radio apps. The emergency radio app is like having a mini-scanner in the palm of your hand.
Now that sounds awesome. More info (name, available cities, etc)?

"Emer. Radio" is the one I have, it works well enough. My only complaint is it jumbles our local radio channels together on one feed.
I have a couple reference applications on my iPhone, "HazRef" and "Emergency Response Guide". I also have a PDF reader and a bunch of reference documents on my iPhone, using "Air Sharing" my iPhone can also be used as a WiFi file sharing server allowing me to access my documents from any computer on a wifi network.
"GPS Formats" not only allows you to convert a GPS coordinate to another format, but it also allows you to email your current location.
