I searched the site and found the theme. I downloaded the theme and looked at all the icons thinking maybe it was for a different program and just named "Deerhunter". There is no deer icon included in the theme package. The rest of the icons are though. I suspect it was something he added to maybe direct to a website or perhaps a video file on the phone itself. It is not included in the theme, it is not showing on any search engine as being a program/game/anything for the iPhone. I am at a dead end and do not have any clue what the icon was for. Sorry.
