iBCNU is an APRS GPS position reporting and text-messaging application for the Apple iPhone. When position reporting is enabled, the application will periodically send out location of your iPhone using either 3G or WiFi network and iPhone's built in GPS receiver. The rate at which position reports are sent out is adjustable. Once the GPS information is in the APRS-IS system, it is shared between all users and you can track yourself or track your friends using this or one of the many APRS mapping sites. When used as a text-messaging tool, iBCNU will let you send and receive messages using the APRS-IS system. You can send short (approximately 512 character) messages to your ham friends for free.
