I just want to point out the following. Apple estimated a delivery date for us. Call that the "Promise." Then, guess what? - We all got shipping notification earlier. That's our NEW Promise.
Actually, you're confusing things.
First you had an estimated "Delivery Date".
Then you had a shipment notification. The shipment notification is not a "NEW Promise", it's a notice that your phone shipped.
Mine shipped, but it said "Standard Shipping".
UPS lists it as "UPS Worldwide Expedited". When I look that up it says, "Delivery within four or five business days from Europe, Asia, and Latin America".
Now, I this may seem complicated, but if I take the Shipped notification and factor in "Standard Shipping" and look at UPS's delivery information, I can expect that my estimated delivery date from UPS of Thursday is probably pretty darn accurate.
Would I like it sooner? Sure, but I'm not upset if it's not here sooner. Seems pretty clear to me.
