Very nice app on it's way through RIM. BlackBerry Protect is on the horizon and it is exactly what is need. Use this free blackberry app to:

• Protect important information on a lost BlackBerry smartphone by remotely wiping or locking the device from your desktop
• Remotely add contact information to the home screen of a locked BlackBerry smartphone so it can be returned if found
• See your BlackBerry smartphone’s location and pinpoint the current whereabouts of a lost or stolen device with cell tower and GPS device tracking
• Find a nearby misplaced BlackBerry smartphone by remotely activating a loud ringer
• Back up data from your BlackBerry smartphone (including Contacts and Calendar; Memos and Tasks; Browser Bookmarks and Text Messages) over Wi-Fi
• Restore your data to a new BlackBerry smartphone, or simply switch from one BlackBerry smartphone to another

All in all this looks to be perfect and we have heard from early testers who are reporting good results.  Look for this in App World in The Beta Zone soon!
