BuddyGuard is a remote wiping application for your BlackBerry similar to SmartGuard. The app gives you the option to wipe your contacts, messages or phone logs.
Instead of using an online account to perform these tasks, BuddyGuard uses commands sent by SMS. For example if you would like to wipe your device, all you have to do is send an SMS to your phone number and in the text field enter bg-wipe "your password" and hit send. Other remote features include lock (to prevent others from accessing the device), List (emails you a detailed listing of what will be wiped), Alert (will play a tone to help in finding your device), and help (sends a list of all commands to you).
BuddyGuard is in Beta, and available via the CrackBerry App Store for free, supporting devices 4.2.1+
