I bought mine off ebay from the UK, ie ebay.co.uk

They tend to charge a small fortune for them here as they are not officially in Spain yet (which to me is still bizarre seeing that the European Union is supposed to be one big state)

On ebay, only buy Iphones from those who have feedback in the thousands and no negative feedback.

I have to say, without a doubt, its the best phone I have ever owned. Once you get used to the finger swishing movement on the ipod screen, you will wonder why they still make phones with buttons and styluses, its flipping amazing!!!!
