Microsoft has updated the how-to section of the official Windows Phone website to include a small tip regarding when location based services are currently active. A small indicator (see above image) will be included in a future update, which be displayed with the other disappearing status indicators that will alert the user as to when apps are using the phone's location.
Microsoft informed The Verge that the update will be included with handsets shipping with Windows Phone "Tango" with existing devices receiving the update once the company has finalised the update with carriers.

Just how long existing consumers will have to wait for the update hasn't been specified, but it's a positive move to fight privacy concerns. We could well see the update including this location indicator being bundled with the new features in "Tango" for Mango users.
