I was able to borrow one of those KIRF (Keeping it Real Fake) iPhone 4. I decided to take some photos of the fake iPhone 4 side by side with the real thing. I must say, it’s really hard to spot the difference between the two by just physically looking at it.
When I got to hold the fake iPhone 4, I noticed that it was a bit lighter than the real iPhone 4. The thing that gave away its fakiness is when I started to turn on the iPhone. It doesn’t have the Retina display of the real thing among other things.
