Okay, so the iPhone I have now belongs to my sister, she let me use it for a year whist she's been living out of the country, now she's returning in a few weeks and wants it back, which is part of the deal.

I want to get a new iPhone 4 anyway, but I'm going to Amsterdam for a month starting around the time I relinquish my current iPhone to my sister.

Now, I see Vodafone do that passport thing. I don't think it's as good as the deal they had last summer where I seem to remember there being no charges, but is there a difference with it being an iPhone at all? I take it the internet would cost loads out in Holland even with passport?
