问题 Does anyone know how to order Facebook places by distance from a search location?

When we think location, we think battery drain, but I guess this is a shortcut and that only GPS really

问题 this is a question we've all wondered about a number of times, and no one seems to have a good answer. How do apps like DataMan run on a regular basis in the background, indefinitely, and still get into the app store?

Yes, I've read all the associated
