If someone asks to borrow your cell phone, or you leave it unattended, beware!
Unless you actually watch them use it, they may be secretly grabbing every piece of your information on the device, even deleted messages. If you leave your phone sitting on your desk, or in the center console of your car while the valet parks it, then you and everyone in your contacts list may be at risk, to say nothing of confidential e-mails, spread sheets, or other information. And of course, if you do not want your spouse to see who you are chatting with on your phone, you might want to use extra caution.
Paraben's CSI Stick can be used to make a copy of all data on a cell phone.
...a new electronic capture device that has been developed primarily for law enforcement, surveillance, and intelligence operations that is also available to the public. It is called the Cellular Seizure Investigation Stick, or CSI Stick as a clever acronym. It is manufactured by a company called Paraben, and is a self-contained module about the size of a BIC lighter. It plugs directly into most Motorola and Samsung cell phones to capture all data that they contain. More phones will be added to the list, including many from Nokia, RIM, LG and others, in the next generation, to be released shortly. (more)
