I work for an import company for a living, so i will give you a little clue as to why all yours are identical tracking wise. apple uses a service we often use called "world ease" which basically makes it much easier and quicker to get through customs. Though every individual phone has a tracking number, all the phones are on one container/pallet/carton or whatever they use and shipped as a single unit to the US. This is so when custom clears it, it can clear them all at once as a single unit instead of the time it would take to clear each individually. It would then get broken down at their sorting facility in Kentucky and from there the phones go off to their happy new homes individually. Fedex has a similar service with the same process done once it gets to Tennessee. So for those of you that did indeed pay for faster shipping, that will probably only come into play from Kentucky to your doorstep. So mine, like many of yours, is also in Korea and according to flightaware.com there is a UPS plane set to arrive in Korea at about 11 am (korea time) which is about 7 and half hours from now. So it doesn't look like our phones have another move until late tonight or tomorrow morning US time. They don't currently have the outgoing flight on the schedule but I'm sure that will be updated later if you want to check back
Flight Finder*. Hope this helps clear up things so you can spend your friday having some fun instead of checking UPS!
