There are a whole set of launch week rules including:

Absolute NO’s

o No Promotions/Contests
o No Countdowns
o No Posters out of the store
o No Flyers
o No Radio remotes
o No Mailers
o No Alteration of Store Hours
o No Swag
o No Tshirts with any reference to Apple or Iphone
o No advertising until 13 weeks post launch

Launch day plans will soon be available. In the interim please do not
modify your store opening hours, speculate on launch plans, contact
the media or create any form of waitlists or advertising related to
the iPhone.

It looks like i{hone launch week is going to be a pretty boring event.

13 weeks from the launch will be right around Thanksgiving and Black
Friday
Maybe there will be some competitive deals then?
