How do i import a blender armature and mesh into unity 3.5?

hey guys i am trying to import a blender 2.63 file with a single armature with multiple bones, and a mesh, into unity 3.5...so what i am doing is importing an asset, then choosing the fbx i have exported it as. then unity will load it but i only can see the arm model, not the armature, yet it says the armature is there...so is there a problem or am i just not looking at it properly?

this is a link to the blend file and the texture...i dont think the texture is neccesary but just in case ;-)
