Think your secrets are safe because you removed incriminating text messages or phone numbers from your cell phone's SIM card? Think again! A new tool, called the Cell Phone SIM Card Spy, lets you retrieve that deleted data. To use the device, which is a USB key, you just put the SIM card into the back of the device and then plug the USB device into any PC. On your computer, you can then read and modify all the info saved on the SIM, including deleted messages! That's actually kind of scary.
