If with the added megapixels the same sensitivity for light per pixel is kept. Added megapixels can be used for digital zooming. preventing the need for heavy and expensive lenscomponents. keep your mobile phone light and cheap. Keeping Steve's remark about 3 Megapixels is sufficient. Properly done digital zoom with8/12 Megapixels seems an excellent alternative for optical zoom in the case of mobile phones. The current implementation of digital zoom in the newer Nokias as demonstrated in this post.
