This just coming in from Pew. I’ll pass it along:

• 28% of cell owners use phones to get directions or recommendations based on their current location–that works out to 23% of all adults.

• A much smaller number (5% of cell owners, equaling 4% of all adults) use their phones to check in to locations using geosocial services such as Foursquare or Gowalla. Smartphone owners are especially likely to use these services on their phones.

• 9% of internet users set up social media services such as Facebook, Twitter, or LinkedIn so that their location is automatically included in their posts on those services. That works out to 7% of all adults.
