iPhone low-cost model concept in 6 colors and plastic case

The concepts feature solid plastic cases that are available in several colors

The designer imagined a model with a 4-inch screen (red model) and one featuring a 4.5-inch display (blue model).

Recent speculation states that the new low-cost iPhone will have the same 5-inch screen as its predecessor and that it will come in six colors.
