Got this email this afternoon from apple where they state the carrier has displayed the wrong delivery date for my new iPhone 3G S.

Thank you for your recent order with Apple.

 Our records indicate that your iPhone 3G S pre-order has shipped.

 Our carrier’s website may have displayed an incorrect delivery
 date for your order. However, we expect your iPhone order to be
 delivered on time on June 19, 2009.

 You can view the most up-to-date status of your order at

 Thank you for shopping at the Apple Online Store.

Apple definately has some major control in the supply chain, including UPS.
