Why won't the facebook icon on my iphone show up?

I downloaded facebook on my iphone 4s, it says "installed" and everything, but an app icon never appeared for it. When i go to the app store, next to the facebook app it just says "OPEN" so i can't re-install it and the only place i can access it. Can someone tell me how to make the icon show up please?

What does this even mean? "Publish your Changes Made in your Itunes on your Computer". I can't see the Facebook icon, and I want to delete it.

  • Why won't facebook show the EDITED version of photos from my iphone? I upload all of my photos from my iPhone to Facebook. I always edit my photos (crop, lighting and red-eye) using the regular iPhone photo editor that comes standard in the photo application. When I upload the edited photos to Facebook, the originals ALWAYS show up. It is infuriating and I want to know what I'm doing wrong. I've tried everything but can't seem to fix the glitch.

  • Why does my Facebook app for iPhone show an incorrect number of notifications on the home screen? On my Facebook app for iPhone, on the home screen, the red number next to the app icon showing how many notifications I have shows an incorrect number. For example it showed 56 when I actually only had 1 notification. I rebooted my iPhone and removed and reinstalled the FB app and neither thing fixed it.
