A great article regarding the security of your mobile/portable devices (including your smartphones) from SMH today: http://ow.ly/8T5I0
This article not only talks about the physical security of your devices, but also the security regarding access to your personal information, and your internet world.
There is also some discussion regarding backups, etc. We used to have all our photos in envelopes or albums, but now they’re on our computers, what would we do if our computers were stolen/lost/destroyed? Please back these things up!
