Twitter meets Craigslist + Google maps on your iPhone

Anttenna’s free mobile application facilitates real-time, location-based, person-to-person exchanges. By turning traditional classified listings into geo-tagged, Twitter-sized microlistings, Anttenna connects people in real-time to others nearby through their handhelds. In less than a minute, potential buyers can search through the Anttenna marketplace to find items or services they’re looking for, all in proximity to where they are at that moment. Microlistings could include finding a concert ticket on location at a music festival, helping a lost pet reunite with her owner, or finding a free sofa right down the block that is in need of a good home.
