Apple has an app for tracking your iPhone/iPad and being able to lock it or wipe it remotely. I found an app called LocateMyDroid that is supposed to do the same thing, but it keeps crashing on my phone(LG Revo, GB 2.3.4). Are there any other apps out there like it that work correctly? Edit: Rebooted phone and tried again, it's working. But several features are only available for a charge, like locking your phone or wiping your phone.
