Facebook's about to make it easier for you to find and share links while you're on the move. The social network has updated its iPhone application with a new feature that lets users search for articles, videos and other web content using keywords. As pictured above, typing a couple of words about what you're looking will bring up a list of related links -- which can then be viewed and shared with your Facebook friends, directly from the app. For now, the feature is only available to people who have an iPhone, but it wouldn't be a surprise to see this on Facebook's Android app in the near future.
