hey furnic..lets hope those international businessmen, on their international travels, dont have any problems with their international warranties hey
i (once) worked for a distributor that handled international warranties on ASUS laptops. the way it worked for them was simple. is it an asus? yes. it is less than one year old? yes. is it broken? yes. ok, proceed with repair.
now, i understand this is apple and not asus, but buying somethig yourself privately does nto count as a grey import, unless the Core guys use a different dictionary.
phone core, then email/phone apple US, and get the truth.
