It's good to understand what "resolution" actually means when considering these types of problems. Suppose you have 2 dots close together. The ability of your camera to "see" (resolve) 2 dots as opposed to a single blob is a function of the sensor and the lens. All the sensor resulution in the world is not going to let you resolve something if the lens has already blurred the image. While sensors have become relatively cheap, optics have not. I think physics alone makes it impossible to have a camera phone lens that resolves anywhere near what these XX megapixel image sensors could theoritically resolve.
