That because in Apple's mind UPS is a "postal service", and 9/23 is really tomorrow. Don't worry - we've know these were coming UPS since like Monday with the first tracking came out. I am still amused that Apple finally fesses up to having shipped it - but won't give up on the 23rd...Well I finally got the shipping email from Apple. It now says delivery tomorrow, but still shows postal service. When I click the track shipment link, it takes me to a UPS tracking number though.
