Apple has been sending all those lucky customers who actually got through to pre-order their new i4 emails. Within these emails, it states that your new i4 will be delivered on June 23rd. So your looks like your reward for getting through Apple’s pre-ordering screen is to get your i4 a day early. Below is a copy of Engadget.com’s confirmation email.
You recently received a Shipment Notification email from Apple advising you that your iPhone has shipped.
This email is to confirm that your delivery will occur on June 23rd. Although Apple and FedEx tracking information may currently indicate a later date, you can check the FedEx website the morning of the June 23rd to track your package to your doorstep.
In the event that you will not be available to accept delivery on June 23rd, it may be more convenient to use our pre-sign delivery option by visiting our Order Status website at http://www.apple.com/orderstatus
Sincerely,
The Apple Store Team
