Unity's Toon/Basic Outline shader doesn't show outlines

Questions & Answers

I've been using Unity 3 Beta for the iPhone. I applied Unity's Toon/Basic Outline Shader on my character, which rendered correctly on iPhone 3Gs (OpenGL ES2.0) emulation. Yet when I built the application on my 3Gs phone, the cube map worked but not the outline.

Here's the CG code that I'm currently using.

CGPROGRAM
#pragma vertex vert

struct appdata {
    float4 vertex;
    float3 normal;
};

struct v2f {
    float4 pos : POSITION;
    float4 color : COLOR;
    float fog : FOGC;
};
uniform float _Outline;
uniform float4 _OutlineColor;

v2f vert(appdata v) {
    v2f o;
    o.pos = mul(glstate.matrix.mvp, v.vertex);
    float3 norm = mul ((float3x3)glstate.matrix.modelview[0], v.normal);
    norm.x *= glstate.matrix.projection[0][0];
    norm.y *= glstate.matrix.projection[1][1];
    o.pos.xy += norm.xy * o.pos.z * _Outline;

    o.fog = o.pos.z;
    o.color = _OutlineColor;
    return o;
}
ENDCG

Please help me figure out why I get outlines in the emulation mode but not in the actual build.

i wasn't aware that the unity iphone was capable of being able to successfully render the outlines without serious hits to performance. here are a couple of links where people are discussing the issue and how to replicate it:
