The budget iPhone rumors started with the same back panels photographed over and over again, but slowly we're getting more believable stuff – first the FCC labels on the phone's box. Interestingly, it's labeled iPhone 5C.
The design of the box is also notable – old iPhone boxes had square angles and a big image of the phone inside. The boxes in the image are all white (no images except a black Apple logo), glossy (plastic?) and have round corners. This would fit the new design direction by Jony Ive, who really streamlined iOS with the latest version and removed all unnecessary eye candy.
