I did a test run and so far it seems pretty good. THE Protection app can wipe, locate or alarm your phone, as well as back up your contacts. The location service is pretty spot on, although it takes a few minutes to hone in on the location (about 3 minutes). The app also gives you the ability to sound an alarm to your phone if you've lost it, even if the sound profile is set to silent/vibrate. Finally you can lock the phone and wipe the data, both which work excellent. If you have asurion through sprint, do yourself a favor and download this app.
