I've asked Foursquare this question by e-mail and Twitter. Others have asked it in the Foursquare support section. I can't find the answer anywhere. Anyway, what I want to know is why does the Foursquare App need to be allow to access my contact information and dial phone numbers? Does anybody know what it does with my contact information and what phone numbers it dials? I think that it just dials numbers of local businesses if you ask it to, so that's not a problem. I have no idea what it does with my contact information.
