Where can I get an unlocked Windows Phone 8

[zxeonz]

I use T-Mobile, and really want to get either the HTC 8X, or Nokia Lumia 810. I cant buy from T-Mobile though, because they force a data plan. I dont want the data plan. Does anyone know where I can get an unlocked Windows Phone 8? Specifically the HTC 8X or Nokia Lumia 810.
