Facebook for iPhone appears on post?

I have been uploading alot of videos this month and everything is fine but today I uploaded one and between the time it was uploaded and the world sign its says "Facebook for iPhone" why? It didn't do that for the other uploads? I used the app and berything for the previous uploads, Can I get rid of it? What do I do?

Why does it matter how you uploaded it? Facebook changes all the time… New features show up every day - get used to change if you are going to be using the internet
