WebEDIT: I misunderstood your question, so please disregard this answer. The Phong shading model assumes a surface normal $\mathbf{n}$ at the shading point $\mathbf{x}$ but it is independent of its type, so either the shading normal or the geometric normal will work.Moreover, this reflectance model requires an incoming and outgoing directions.
