When leaving your facebook logged in on the iphone app?

[Ken Doll]

Does it use internet? Like as in when your going about your phones usage but just don't log out of your facebook through the Facebook application does it waste allot of your internet if any?

It doesnt use any internet because you are not connected to the internet when you leave the application, it just remembers your log in so you dont have to type it in again. Your friends will see you as offline too.
