This seems like the most rational explanation for this which is why we won't see anything for another couple of days. The planes need to reach Louisville and then the phones make their way to Dallas and once they sift through how many they got our orders will start updating with tracking information. I don't know why AT&T doesn't get more information from Apple regarding how many phones for AT&T are on those planes or maybe AT&T does know but they couldn't care less about updating information for their customers, the whole under promise and over deliver thing.Possibly, yes. I suppose Apple orders show up earlier in UPS's tracking system because they ship from China to the destination/hub in Louisville and many ship right from there to more regional fulfillment centers closer to where the group delivery sorting is pointing to, but all within the UPS system. Other carriers such as ATT seem to have their own fulfilment centers that UPS hands off to for inventory check, then out of the fulfillment center back to the carriers for delivery.
