We're seeing just the first wave of the cell phone revolution. The handiness of it and the fast developing technology bringing the image to its end use will further erode both the "real" camera benefits as we know it and the fees for its related photography services.
I can imagine, for example, that soon a wedding photographer's shooting will be the core images with the photographer then serving as an image editor, culling shots from guests' cell phones and incorporating all into digital streams and products. I'm sure some wedding photographers are doing something on this track now.
Art show photographers have already seen sales decline because of the improving quality of tourist snaps that are easily edited in-camera and can be forwarded to their phone list, social sites, or to any on line print provider. Maybe that's why so many art show exhibitors reach for other forms of presentation (metal prints, large canvasses, heavy HDR, etc.) to try to keep ahead of the quickly developing customer-produced work.
All in all it's an exciting time, akin to the more gradual, comparatively, transition from film to digital.
