How to put texture on cellphone screen

Hi,

I have a 3D model of a cellphone and I would like to put a texture on the screen only. How can I put a picture of my windows desktop on the screen of the phone in Blender?

Thanks,

Short answer would be to apply an image map to the material you have assigned to the screen. Read here for more info https://www.blender.org/manual/render/blender_render/index.html
