That's not good! I know it can annoying when your phone is moving by itself. It's important to have a properly working phone at all times. Let's get this fixed. Since, you have already completed a Blackberry Manager backup of your entire device. The next step that I would recommend is going to be a Hard Reset(Wipe Handheld) http://vz.to/HrQkCY, per it sounds like the software is corrupted. Once complete, you can use the Blackberry Manager software to reload the latest backup to the device. Keep me posted.
