Submission + - Closed source cellphones are a security nightmare (cnet.com)
CNET News writes "CSI Stick grabs data from cell phones"
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.
I use mobile knox, a secure storage application for my important data but I would be very upset if someone grabs my telephone list, SMS, and whatelse from my locked phone !
