SmrtGuard is one of those apps that just works. It gives you peace of mind that your device is safe and can be remotely wiped of all data should it ever be lost or stolen. You can backup/restore data, remotely wipe and locate the device, protect your SIM from being swapped out and more. I love having it installed as it can be used both as a backup tool and has loads of security features. Everything can be managed from an easy web-interface (check out what it looks like after the jump) and it just does what it does. Hit the video above for a quick look. SmrtGuard is available in the CrackBerry App Store for monthly, semi-annual and annual subscriptions. A free version is available in BlackBerry App World that gives you the remote tracking, remote wipe, personal guardian and SIM guardian all for free (so you have no reason not to try it).
