Location services
I noticed (I think in the dev thread at some point) about Location services not working in CM9. I noticed something similar on my own NC when I installed CM9 (on both SP2 and one of the unofficial nightly builds). I read someone say that a different version of Maps will resolve this issue, but I have yet to determine which one, and if this is actually true.
Anyway, I realized this morning that while location wasn't working for most of my applications (i.e. Maps (when you try to have it go to your location, it says "Please enable a My Location source in system settings"), Facebook, etc) that Latitude was updating my location, even though Maps refused to find my location.
To add to the mystery, I also installed TetherGPS from the market (you'll also need to enable Mock Locations for this app to work), and even without tethering it to anything, the location stuff (for all the apps that used to not work) magically start working!
Has anyone else noticed this? Any idea why this is happening?
