Beam It! allows you to wirelessly â€œbeamâ€ your contact information to another iPhone or iPod Touch, and features automatic discovery of other handheld devices near you running Beam It! Download it for free from httpp://go.arctouch.com/beamit
Beam It! uses the iPhone OS 3.0 Game Kit APIs to automatically discover other nearby iPhone and iPod Touch devices running Beam It!, and then uses Bluetooth to spontaneously create an ad-hoc peer to peer network to share contact information.
ArcTouch is also providing the full source code with free usage rights to members of the iPhone Developer Program so they can see how to use the new peer to peer APIs in the Game Kit framework. Visit http://arctouch.com/beamit for more information and download instructions.
