For anyone having issues getting their UPS tracking number to work:
Type your postcode without any spaces. I.E - SE13DG, not SE1 3DG.
Strange, but that seemed to do the trick for me.
Hasn't changed a thing for me. I called apple and they have me a 14 digit tracking number but it hasn't worked in any of the courier sites
I know it's coming tommorow but I wanna see it every step of the way!
