I am building a "DIY Cellphone" project (http://2loo.com/ax). I have ordered all the components in the Bill Of Materials (http://2loo.com/ay). I put together almost everything when I stumbled upon a component that I don't know what it is. It is the component in the figure below (Taken from: http://2loo.com/aw). I think it says "D" or "0" on it. Is that a capacitor or a jumper?
According to the cellphone schematics (http://2loo.com/az), one capacitor and two coils are supposed to be there. However, those are missing from the bill of materials and are also missing from the figure above.
