Is there an iAd daemon?

Anyway, I'd hope that explicitly disabling all location services would do just that. If headless apps were still powering on the GPS and triangulating cell towers and wifi... well, that'd certainly be misleading. But I doubt that's the case.

If it were powering on the GPS that would be significant. Aside from the privacy perspective, many people power down GPS to save the battery which is something which should absolutely be something which remains under user control.
