Chinese people go crazy for iPhones, when the 6 was released my friend had a trip scheduled to go back home to Shanghai for a few weeks, EVERY ONE of his friends asked him to bring them one (or more) unlocked iPhones, and they were happy to pay well over store price, as the iPhone got released a month late there.

He ended up bringing them only for his closest friends, as otherwise he would have been arrested at customs :)
