I don't know if I am allowed to paste a link so I won't but the store from which I bought my phone (as well as user Denyno) seems to offer a gold-colored edition of the v3 for 6$ more than the price for white.
Has anyone heard of a limited-edition gold-colored v3?!?

It's just gold colored plastic. There is nothing special about it other than a different color.

Yep, it's also available in other stores (pre sell)
