I guess I'll run through the proof.
- Music icon colors are flipped
- Clock hands are too long - It's not the camera angle
- More than one of these supposed phones have been posted online
- Green color of the Phone and Messages apps are pre-iOS 7.1
- The build number of the supposed iOS 8 this phone is running on is lower than that of iOS 8 Beta 5, but seems to include elements we haven't seen.
- The Touch ID sensor appears to be made of plastic
- The aluminum enclosure does not appear to be as high quality as recent leaks
- The Touch ID unlock animation is off
- Touch ID takes too long to register
- The background on the phone is not a stock Apple background, yet it is seen on all 3 of the phones that have "leaked" out.
- The Apple on the back is printed on, not a separate entity.
- There are no additional apps, songs, pictures, or videos on the device, yet something is taking up 700 mb of storage.
Need I say more? And my current phone is a 5s.
