I was posting to another security blog (emergentchaos.com)this afternoon about the importance of data destruction on cell phones and palm devices. It all came from a little test that Trust Digital did on ten phones they purchased from eBay. Surprise, they found lots of data. Read my post. This is, of course, a follow on to my recommendation that organizations and individuals physically destroy hard drives before disposing of their computers. Greg Keiser had a great write up on the issue as well.
