Cant find newly added contact iPhone

I have an iPhone 4S, just upgraded from iPhone 4 where I had the same problem:

When I add new contacts I cannot subsequently find them in my contact list. However when on of these contacts calls me my their # is recognized and the screen will display who is calling - name, just as I had entered when adding them to my list.

I have tried to search in "all contacts" and in every contact folder.... all to no avail.

Can anyone help me out?

Much appreciated in advance.
