The e-mail from Apple (AAPL) notifying me that my pre-ordered iPhone 4S had left Shenzhen, China, early Monday and was set be delivered in four days popped into my mailbox at 2:07 a.m. EST -- two days and 21 hours after AT&T's (T) servers finally let my order go through.
9to5Mac meanwhile has posted a notice from Sprint (S) that an iPhone ordered through them had shipped at midnight Sunday and would be delivered "Overnight: Next day PM."
We'll believe that when we see it.
