There are two apps that I must recommend to everyone. First app is the Where's My Doid. Ever lost your phone & you go to call it to listen for the ringer, but it's on silent mode? Now you can text your phone from another phone with the secret word & your phone will start to ring. it will turn the silent ringer off & phone will start ringing. Second is the GPS Tracker which lets you track your phone in real time. If your phone were to be stolen,you could track it from online.
