If you signed in to your Facebook account when you turned on and set up your phone for the first time, that means your Facebook account is linked to Facebook for HTC Sense on your phone. (If you did not do this, you can set up Facebook for HTC Sense at any time. For instructions, see Adding a social network account.)

With Facebook for HTC Sense, you can:

• See all your Facebook contacts in People.
  
• See Facebook photos right in the Gallery application.
  
• Check your friends' Facebook status updates in Friend Stream.
