Hey everyone, I'm Irish and in the states for the Summer. I'm thinking of picking up a 3G iPhone while I'm over here because of the strong conversion rate. I would like to buy the iPhone and use my Irish sim card in it when I get home? I presume this is still possible? Will I run into any trouble when I go to buy it in the Apple store, will I need to activate it? Thanks for all replies and advice, Kev.
