For those that tracked with their phone number, how exactly did you do that? When I go to UPS I see no option to put in a phone number?
Go to the shipment tracking page on UPS website and click the Track By Reference menu item in the left column.
In the Shipment Reference field, enter the phone number thats associated with the shipment. This may or may not be the cell number on the iPhone it might be the number associated with your billing address.
Select the destination country and then fill in the destination ZIP code (or Postal Code if youre outside the U.S.). Click Track
