Here's how you do it!
 | In the facebook app, tap the menu-button in the upper left hand corner of the screen, just above the "status" button. |
| A menu should slide out, allowing you to select "Friends". |  |
 | Once your friends-list opens up, choose the action-button in the upper right-hand corner. |
| Choose "Sync Contacts" and you'll be taken to a screen with a couple of different options... |  |
 | Turn on "Syncing," and if you want to replace the photos you have for your existing iPhone contacts, also turn on "Replace Photos". |
| You'll be asked to confirm that you want to add facebook information to existing contacts. |  |
 | Voila! You're done! Your information will sync, and from here on, facebook will help keep your contacts up-to-date. |
