I ordered a 4S from apple.com yesterday around 4 PM. Got the confirmation email about my order being processed, but how long does this usually take? I chose the $12 next day shipping and it said in the order processed email delivery would be 10/23. I checked the status and it said preparing for shipment. Are their dates usually pretty accurate? I ask because I believe there is signature confirmation.. I really hope it does come in tomorrow as promised because my classes are cancelled tomorrow and I will be home to get it. And I can return my 5 when my 4S comes in.. running out of the 30 days. Just wondering what anybody else's experiences have been with the shipping times.
