How do I sign off of Facebook on my iPod touch?

IPod touch Facebook app problem?

• Ok I sign on to facebook and try to talk to my boyfriend on the chat but when I click on his name it just closes out and brings me to the ipod touch screen. Also when I look at his profile it says add him as my friend but he ALREADY is on my friends list and the only way I can write on his wall is it I click on a previous post I did to view his page..Some other people's pages are also like this. Why does it say add as a friend if he already is my friend??

• Answer:

  Reboot your handset. If that doesn't work then you may need to remove the application and reinstall it. You can do this by holding down your finger on the application til it starts shaking. Then hit the black "X" to remove the app. Now go back to the app store and reinstall.
