Now that the U.S. is catching up with the rest of the world's mobile phone addiction, we can use our nimble thumbs to engage in some quality worldchanging. We've learned a lot about what's possible with mobile from Google, Apple, and Nokia in the past year alone. Now is the time take the baton and move forward.

Tomorrow and Saturday, the Big Brain Boy's Mobile Media Summit will feature presentations from some of the world's top mobile innovators and producers alongside panels discussing how mobile technology can be used to promote social change on a global scale. Topics include Games4Change, Mobile Banking, and The Art of the Possible.

The summit will also feature the premiere of the music video "Surfing at 32ºF," directed by Mike Hodgkinson and an advance screening of Take Flight, Juliet Landau's documentary of Gary Oldman's process of directing a music video by Chutzpah, a Jewish Hip-Hop band. (Watch the trailer below).

There will be opportunities for open discussion, and an opening reception at the home of Ari Arad (Iron Man).
