How to tell if my iPad 2 is Refurbished?

Hello,

Please be nice I'm new here and apologies if I've posted this in the wrong section.
My friend has recently bought a iPad 2 from eBay thinking it was brand new as the auction stated it was brand new. We were using eBay uk so we thought the item would be from the UK. But we were surprised to find that over two weeks later it had been shipped from the states. And the code on the back of the box read FC769LL/A RFB IPAD 2 WI-FI 16GB BLACK-USA.
I've typed the code into google and its come back as refurbished, but the box wasnt the usual plain refurbished unit it was a proper iPad 2 box. And I must add the box was not shrink wrapped just had apple stickers holding the sides down. We've contacted the seller he assures me it is brand new, and said the box would have been different. But that code is bugging me and the fact that it was not shrink wrapped. Could anyone help me on this matter or direct me a website where I can check, or should I just pop into my local apple shop. Many thanks in advance for any replies,

Hi ,

Many thanks for all your responses, just to confirm the item is indeed refurbished and the seller on eBay has agreed to refund me. In the end it seems I had to ring apple, as I was going round and round in circles. And they confirmed it, the other poster was indeed correct DK signifys a refurbished unit.
Thanks again,

Darren
