Graphics come out ugly on Nexus S after doing glRotate

Hi!

I am developing a 2D app in which I am using OpenGL ES to display the graphics. It is done in the most basic manner, by having textured quads and orthographic projection.

It has worked very well, until I received my new Nexus S phone. On this device, but not on any other as far as I have seen, graphics which are rotated with glRotate comes out ugly and aliased:

On the emulator which runs the same screen resolution, the image looks much better:

Any ideas as to what can be causing this? Are there some hardware issues on the Nexus S, perhaps, or is it something I am doing wrong?

I have tried to adjust glShadeModel and glHint with all available options, but still with the same result.

Thanks for any input!
