Apple: Core Location Not for Use Solely for Serving Location-Targeted Ads

Apple Developer Connection:

If you build your application with features based on a user’s location, make sure these features provide beneficial information. If your app uses location-based information primarily to enable mobile advertisers to deliver targeted ads based on a user’s location, your app will be returned to you by the App Store Review Team for modification before it can be posted to the App Store.
