looking for 2d outline shader

Unity Engine
1

Hi,

I want to put a black outline around a plane or other custom 2d shapes I’m using in my scene (using orthographic view). The Toon shader I’ve found all use the z-index for creating the outline effect. Is it possible to achieve a 1 pixel outline with another shader? The optimum would be a non-pixel shader as this should work with an iPhone. However, with Unity 3 and iPhone 3GS a pixelshader will be fine as well I guess.
Thanks in advance for any help!
