iPhone 3G Application
Tapulous has developed an iPhone 3G application which "allows two iPhone users running Friend Book to share their personal contact information by shaking their phones in close proximity to one another." Video after the break.
The app works, I'd guess by sending the closely matching accelerometer data back to the Tapulous server, where they're matched in the cloud and info is swapped.[via Gizmodo]
