When you picked up your Nokia Lumia 920 a few months back you probably had a color in mind before heading to the store. Maybe you wanted Cyan or Yellow to stand out from the crowd. But you get to the store only to have your selection limited to whatever was on hand. You could have waited for more colors to come in, but you said screw it and took black because you wanted that Windows Phone 8 goodness right then and there. You could throw on a case and get a new color, but you’ll lose out on the beautiful industrial design of that high-end Lumia.
Why not just swap the shell?
