Opengl es != opengl. A lot of code must to be rewritted to port an opengl game to opengl-es. Opengl-es 2.0 is more like opengl 3.0. I have a cool 3D game that i developed for iphone some months ago. I am awating for the release of the new maemo device to port it to freemantle.

Sorry for my english, i know it is bad
