Social Search may be the killer app for the new 3G iPhone 2.0 release.
Loopt launched its native iPhone social search app onstage at WWDC, Apple's Worldwide Developers Conference. The free application will connect users with their friends by using location technology built in to the iPhone, Like Google Maps, Loopt will drop pins onto a map showing users where their friends are.
CNET reports that Loopt also offers other social-networking features, such as calling, texting, and sending invitations to meet up. The example used was seeing if any friends are in your area for lunch. Once you have located friends, you can send them an invitation for lunch, and if they agree, you will be one touch away from directions to their location. As Sam Altman from Loopt put it, "You will never have to eat alone, or at a bad restaurant again."
