This particular topic has been discussed to death lately. It's really not that big of a deal. Apple is doing this to aid in the phone being able to Triangulate it's position in relation to cell towers (when gps is unavailable).

Also, the phone is NOT constantly tracking your location. It only logs a new location (a) when you launch a location-aware app, e.g. Facebook, Maps etc. And (b) when you have never been to that location before. It does not log the amount of times you have visited the location.

I suspect Apple is planning to do something cool with this Data, because of the way it is synced across Computer and Phone. Keep in mind however, the Data cannot be used to Track you constantly, only to see where you have been in the past, but, the log will never update to show that you visited a certain location more than once.

Hope this helps!
