How much cost unlocked iPhone 5S

A 16 GB unlocked iPhone 5s goes for 649 U.S. dollars. And, here is the result I got from a currency converter. conversion result 649.00 United States Dollars = 4,172.62 Sweden Kronor

Okej. It is not so expensive I think. If I'd buy an iPhone 5S from the U.S, would I like to active it in other country and use my own language? I mean, I can open it and activate wherever I am World wide?

yes if you are planning to buy a iPhone 5s factory unlocked it is world capability for then you have the oportunity to set up as you want is up to you however regarding to apple store there are a waitting list specially for the gold color apple didn't mention any date but is longer then silver about 3 weeks and finally space gray shorly

Okay, Fine! So if I understood you it will take about 3 weeks to buy iPhone 5S silver color? I think it's so much fine and cool. Can you link me a site for shopping where I can buy it in U.S? I don't know how long time waiting list for shipping if its already about 3 weeks.

This has the potential to go seriously wrong. As far as I am aware, you will only be able to buy a fully unlocked iPhone from Apple itself (either from their online store or a bricks and mortar store). I very seriously doubt that they would ship overseas. There are ways to circumvent this, but they only introduce more cost and potential for problems (companies who will buy on your behalf, have the item delivered to them, and then ship it to you). You could probably buy one through eBay, but that has serious risks. There is the not insignificant matter of ensuring that the device you get will work in Sweden, which means that you will need to ensure that you know if the phone you are buying will be CDMA or GSM and that this is compatible with your carrier. Also, the warranty and support would only be valid in the US. As I said, this is far from straightforward, and should only be considered if you are fully aware of what is involved and what might go wrong.
