openGL 3.1 and Shader Model 3?

I have a mid 2011 Macbook Air with Intel HD 3000 graphics. I've tried to run certain games, and I get one of two different errors depending on which game I wish to run.

1. Graphics card does not support openGL 3.1

2. Graphics card does not support Shader Model 3

I know that my MBook Air has openGL 3.0, and I'm not sure which shader model. Does anyone know where I can get an update or drivers to allow me to use Shader 3 and openGL 3.1?
