This.I think it is something to do with leprechauns, they're real you know. I haven't seen one myself but I know a man who knows man who seen one.
I hope its not the green 1520. I waited for the green 1520 for a month after my two year Lumia 900 contract ended but I couldn't wait anymore and got the black 1520. That'd be so frustrating if it came out a little more than a month after I stopped waiting.
Just do what I did and buy a replacement back in the colour you want.
I don't think I want to go that far to get the color I want. I don't want to take the chance of accidentally damaging the hardware. And if I did get it replaced right, it wouldn't have the same Nokia-quality durability that it has now.
