As of right now we do not have an identifier for iPhone lenses in our database because it still is a pretty small segment. At some time in the future if the segment picks up we'll look to adding them in.
I see the iPhone is still the most popular camera on www.flickr.com/cameras
so I look forward to that future time when lens identifiers become a reality. Since getting the 5s, I've been really impressed with its camera and wished there were some site where I could browse a selection of lens accessories for it. Google and ebay searches just seem to uncover plastic junk that doesn't match the quality of the iPhone, so I had pinned my hopes on a speciality site like gdgt to clear the path to the quality stuff.
