is the link that you provided above is deliver the iPhone worldwide?
because I'm from Asia so if I buy the iPhone from that website will it work in my country?
The first link provides shipping worldwide for free, but will you buy it from other countries when you can buy it around you? If you buy from other countries then you need to pay some more money for the import tax which wont be small amount of money. There is no benefits to buy something from other countries while you can buy it on your own country.
