I doubt Colorware for three reasons.
1. Colorware covers up the iPhone lettering and everything else. Only thing visible is the Apple logo
2. You can still tell there are two pieces with Colorware. This has one piece.
3. There's a more pronounced curve on the back of this photo compared to the current iPhone.
So either it's a really good shop, a really good case mod, or it's new. But I highly doubt it's Colorware.
good summary!
