If anyone would like to track their iPhone, I've found a way to do it through UPS. Even though my iPhone still says "preparing for shipment" on the apple website, I found out that it is currently in Kentucky and has already been shipped.
If you go to the UPS website and create an account.
Then go to "tracking". Then choose the "track by reference" option.
Where it says "Shipment Reference" enter the telephone number associated with the shipment. Might not necessarily be the phone number on the iPhone, might be the number associated with the billing address. Then select the destination country and the destination zip code.
You should be able to see if your iPhone is in transit!
