A new backup solution has been launched by RIM which adds security such as remote locking and device wipe. Along with this you can also find out where you device is if lost using remote locate feature and also has a function to switch on loud ringer is you can find your device in the home. All free I suppose in a similar vain to Mobile Me.

You need to register with your Blackberry ID, if you have blackberry appl world installed in your blackberry its the same ID as the one you use there.

Useful feature and simply implemented considering its free and I don't think many will complain.

Sounds interesting, especially if it remains free of charge.
