How to protect personal data on old devices you sell
Thinking of selling or giving away your smartphone or laptop computer? If you have a BlackBerry or an iPhone, go right ahead. But if you have an Android phone or a computer running Windows XP, you may want to hold off.
It turns out that it's almost impossible to get rid of personal information from some devices, even if you follow the manufacturer's directions for wiping the device clean.

He bought 30 electronic devices from Craigslist — mostly smartphones and laptops — to see how effective people were at removing personal information from their gadgets before selling them.
