We're launching the second in our expanding "Vision" series. This new one - The Future of Wireless - looks at the broad impact the move to mobility is having on companies and individuals through the eyes of leading analysts, cutting edge entrepreneurs, savvy government types and others. The series, sponsored by Earthlink Wireless, looks at the ways people and businesses are connecting, interacting, finding and sharing data, improving business processes and productivity, and more.

Our first interview: Dennis Crowley and Alex Rainert, founders of the mobile social networking service Dodgeball.
