Hat tip to Aaron Lintz and a super secret group for starting this discussion a few weeks ago.
To sync LinkedIn contacts with personal URLs, Locations, Phone numbers, etc:
Go to office.live.com and sign in with your Hotmail, Outlook, or Live account.
Then on the apps screen, go to People.
At the top of the screen, go to Manage > Connect to Social Networks
Connect your LinkedIn account.
I like the search functionality in Google so I synced my Outlook contacts to Google.
