In this April 22, 2011 photo, University of Iowa sophomore Autumn Bradfish, 20, of Lake Zurich, Ill., poses for a picture at the Iowa Memorial Union in Iowa City, Iowa. Bradfish said she had heard little about the reports of her location being collected on her iPhone and she said she was not particularly concerned about the practice. "If they use it just for ads, I don't see that as a problem. Facebook does that. If I'm going to have ads thrown at me, they might as well be relevant to my location." (AP Photo/Ryan J. Foley)
