iOS 6 was released yesterday to the masses and it includes many changes, many of which are not easy to spot until you play with this new version.
One such change is where the Location Services are placed. Some apps leave location services on in the background and users may feel the need to turn them off.
When they feel that need and go to turn them off they might not find the setting on iOS 6. Under iOS 6, Location Services are placed under the Privacy settings (Settings > Privacy).
So, there you have it.
