Uh, there are a lot of differences between OpenGL 1.4 and OpenGL ES 2.0. OpenGL ES 2.0 is totally shader based, while OpenGL 1.4 uses only fixed functionality. Although there are some functions that are the same, OpenGL 1.4 and OpenGL ES 2.0 are substantially different. OpenGL ES 2.0 is much similar to OpenGL 3.0, than to previous versions. In fact OpenGL 3.0 is created out of ES 2.0.

So, my advice is to find OpenGL ES2 Programming Guide, if you plan to write programs for ES2. OpenGL 1.4 is too old. More than 7 years! I don’t understand why did you choose that particular version? Maybe because your laptop supports only that. If that is the case, forget about ES 2.0, because all simulator require at least OpenGL 2.0 to emulate ES 2.0. It is required because of shaders!
