How do I restore my contacts icon

I have just received an Iphone 4 from my company. The first time I turned it on, it went thru the usual setup routine and all was

well. I also still have an Ipod, an Ipad 2 and an Ipone 3GS. All are connected to Itunes on my pc. Life is good, except for one

small glitch. My Iphone 4 has no "Contacts Icon". I don't know how to get it to show. It should have just been there, like on my

other Apple products. I do have Contacts that I can reach when using the phone part and other things, but no Icon on the desktop.

How can I make this thing show up ? Everything else seems fine.
