WHEN YOU SELL YOUR PHONE, YOU SELL YOUR DATA

Researchers who examined 49 secondhand mobile phones were able to extract an average of 227 pictures, e-mails, and other items per device, and they found that about half the phones contained sensitive personal items, including images of nudity, and one contained sensitive business information. Using standard forensic tools on the phones, which were purchased on eBay and in a pawn shop, the researchers were able to recover deleted items from 31 of the phones.
