For those trying to track using a FedEx reference number ... I have a package coming for which I have the tracking number (not from Apple). I tracked it and got the reference number off the tracking info. I then tried to "track by reference" number. After doing it several times I got nowhere. One time I put in my phone number and also the reference from the other package. That time it showed two shipments with the status bar of "in transit". When I clicked on those I got "Unfortunately we are unable to retrieve your tracking results at this time. Please try again later." FedEx definitely has problems tracking by reference, so don't even waste your time. (UPS, on the other hand, has a great system with My Choice but they don't show any packages coming to my address.)
