Most of my mobile contacts have mobile/landline along with work phone and much more.

Why I can't see the caller number, I can never identify from what number he is calling or at least (work, home..)

This makes the whole mobile useless for me without such a feature in ALL other mobiles

try not to assign multiple numbers to one name or follow this example :
Mark home *** *** ****
Mark work *** *** ****
this is one way to do it...a pain in the *** though..
