Ham Radio Callsign Lookup

This Web app provides an iPhone-compatible lookup of Amateur Radio Callsigns. It provides the name, address, and license class (from the FCCs public records) of any US-Licensed Amateur Radio Operator. You can search for individuals or clubs by callsign or name, and even look up someones old callsign to find out what the new one is.
