Yes companies have played games with the yellow pages forever, but I do not think that putting a space in front of your business name would get you at the front of the yellow pages listing.
This technique seems to really work to boost sales, the " Solitaire City" that is right now at the front of the list, (do not know how long it will stay there before they get leap frogged), has been steadily creeping up the Top Apps list. This game is $9.99, certainly not cheap for Solitaire.
