I have location services on and they seem to be working with things like weather etc. It does not work with reminders. I've done a ton of research on this forum, and have not found the answer, so I went to the Apple store. The Genious restored my phone from scratch, turning on location services when the phone originally started up. Then we tested location services in reminders, and it worked perfectly. Yeah!!!! I then proceeded home to restore my back up, recognizing the risk. Well, sure enough, it broke my location services in Reminders again. When I go to Settings and drill into Location Services to make sure it's on for Reminders, Reminders does not even appear as one of the applications. Apple can't explain it. PS: I'm having the exact same issue on my wifes phone and both of our iPads as well.
