The Facebook app for the iPod touch allows you to search for new friends, view your friends’ profiles and unfriend people from your account. Many of these options are accessed using iOS-specific buttons. For instance, the Apple-designed “Send To” button provides you options for adding friends to your “Favorites” list, sending messages and unfriending people. As with Facebook’s website, unfriending individuals on your iPod touch is final and cannot be reversed without requesting that person as your friend again.
1. Tap the Facebook app icon on your iPod touch’s home screen to launch the application.
2. Tap “Friends” on the Facebook app home screen.
3. Scroll down and tap the name of the person you want to unfriend.
4. Tap the “Send To” button in the top right, tap “Unfriend” and tap "Unfriend" in the pop-up window to remove the individual from your list of Facebook friends.
