Here's the overview of the report (html, questions):
A new report finds that 74% of smartphone owners use their phone to get real-time location-based information, and 18% use a geosocial service to “check in” to certain locations or share their location with friends.
Over the past year, smartphone ownership among American adults has risen from 35% of adults in 2011 to 46% in 2012. This means that the overall proportion of U.S. adults who get location-based information has almost doubled over that time period, from 23% in May 2011 to 41% in February 2012. The percentage of adults who use geosocial services like Foursquare has likewise risen from 4% in 2011 to 10% in 2012.
