Google+ has been updated to pull data from Google Contacts and display it in the profiles of your Google+ friends, starting today. If you're a Gmail or Android user, chances are you've got a well-populated contacts list, and now information on that list will automatically show up in a Google+ user's "about" section — for your eyes only. It's a minor update, but a useful one, and something that most smartphones and other services already do when they sync contact information from multiple sources.
