iPhone 4S shipments begin

Units pre-ordered early last Friday are due to arrive by end-of-day this Friday

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.
