OK, I'll admit it: I just rid my cell phone's address book of a series of people I hadn't spoken to or seen in years. I'm not sure why it took me so long, save for the fact that every time I get a new phone I have the salesperson transfer my SIM card into my new device.

This month's Shape says if you do anything this month, you should clear out your cell phone [1], which got me thinking about how cluttered and outdated most of our address books are.
