SpriteManager works on the computer but not phone

I am generating a bunch of 2d sprites using the SpriteManager script and it all works fine on the computer(even with graphics emulation on iphone) but for some reason it won’t draw any sprites on the phone. Has anyone else run into this problem, or does anyone know how to fix it?

So it turned out that my material was Transparent instead of a Particle shader and I guess the iphone didn’t like the transparent shader.
