I deleted my facebook app, because it was freezing everytime i posted a new post. I thought reinstall would help the situation. I went to app store and tried installing it again but it said that it is installed already. I dont see it anywhere on my phone. Help! -Tried Installing through itunes-Nothing -Redownload it on iphone- Nothing! -Shut iphone down and restarted-Nothing -Holding Top Button And Home Button- Nothing Help ME!
