title: CLLocationManager not prompting the user and returns NULL
body: <p>Till yetsterday everything was working fine on my iPhone. Starting today, I noticed that CLLocationManager does not prompt the user "this app wants to use your location" and proceeds to return me null in the didUpdateToLocation. I have tried signing my app with dev provisioning, adhoc and prod profiles. Also, I am making sure that I delete the app before trying this. Earlier the moment I would run the app first time, it would prompt me for push notifications and GPS prompt. But now, none of these prompts are showing up. </p>
  
  <p>My App does a CLLocationmanager startupdatingLocation in AppDelegate --> applicationdidLaunch and applicationdidLaunchwithOptions. Also, CLLocationManager does not call my didFailWithError.</p>
