Cell phone insecurity....

Phone hacking (aka Phreaking) is no longer just in the domain of the highly skilled and technically motivated that it was in the early 1990s. No longer do you need to get components from Radio Shack and modify them to do nefarious tasks.  You can simply buy a Cellular Seizure Investigation Stick (aka CSI Stick), and learn everything you could ever want to know from someones cell phone.  This type of stuff has been possible for a long time, and it's why my general security talk I give to high school students involves telling them to NEVER leave a cell phone unattended and unsecured, unless they don't mind someone eavesdropping on their future calls, getting access to all text messages and photos, etc.  This just makes it easier.
