Help! Downloaded Facebook on my iPhone and it disappeared. Can't delete it because it's gone, but it's showing that it's installed?
Do iTunes & find it on your list & delete it that way if u can't find it there then go & use a older back up from there that u know it on . Good luck
Try turning off if that does not work remove the battery and put it back in.This should reset your phone.GOOD LUCK
Try resetting your phone settings and this will get rid of the Facebook installation completely and then try downloading it again if you want to.
Hold power and home button until phone shuts of. keep holding till the apple symbol comes on again
Sink your IPhone in your computer. All applications it will appear again. Even the Facebook application.
