I ordered two iPhones a few minutes after 12:00AM PST. I used the UPS reference number trick to find the devices, and both showed up shipping from China on 9/16, and scheduled to arrive on 9/21.
Last night, I went on UPS.com again and searched for reference numbers (my billing phone number, like the rest), and I was surprised to see now 3 tracking numbers, the original two from China, and a 3rd one from Addison, IL, with a weight of 2lbs. This matches exactly what other people are seeing as far as weight and location with shipments from IL. The shipping method on this package shows Next Day Air Saver, with a delivery date of 9/21.
Anyone else have this? Could it really be a 3rd phone? I'm absolutely positive that I only ordered two devices.
