Has to be someone that has painted it. Here's why:
- If this were even close to a legit rumor, sites like The Verge, MacRumors, 9to5Mac and Engadget would have reported it a long time ago.
- It's not a "Slate" iPhone 5 with different lighting because if you look at the 4th photo, the Power button is most definitely black and the phone is not
- The photo quality is terrible, if someone really did have a dark blue iPhone 5S. Then show me the home button and do it in a room with a light on. Not in your parents living room with nasty brown couches.
EDIT: Nevermind, TC already confirmed it as a fake
