annoying batberry-ness

i downloaded the Batberry theme. it's to hold me over til this one person is done making my Joker/dark knight theme.

i downloaded it and it has the facebook icon now in my apps list. i had this, but i deleted it a while ago. i click on it and it takes me to this page to d/l facebook app. i do it, and the icon disappears. i think, alright cool. i go to my apps list and delete it, restart the phone, and there is the lovely facebook icon with the page to d/l the facebook app. i have the icon hidden right now, but is there any way to get rid of it?? it's not in my apps list.
