Tom let me know that SmrtGuard is now in public beta with some very interesting features. It comes with the regular anti-theft features like finding your BlackBerry if it is lost and remotely wiping it or making it sound off so you can find it. The cooler part is that it also lets you backup your BlackBerry OTA so you can easily switch devices or export your backup data.
SmrtGuard can backup your contacts, memos, tasks, events, call logs, & emails to their servers. It will backup thousands of contacts and the pictures for your contacts too! You can also set it to be an emergency button that lets you hold down the menu key for 5 seconds and it will email, SMS, or phone people letting them know you need help.
The location features on the device are through GPS and it will gracefully fall back on cell phone tower triangulation if it is indoors or your device does not have GPS.
