According to Mac Otakara, the latest issue of MacFan contains images of the low-cost version of the future smartphone.
The drawings show two smartphones with 4.7 and 5.7-inch displays on bezel-free devices with rectangle-shaped volume controls.
A camera with a single LED-flash on the rear is also listed among the specs.
The dimensions of the smaller version are 137×66 mm in length and 7.0 mm thick. The bigger model measures 157×77 mm and is 6.7 mm thick.
Last month Mac Otakara reported that the iPhone 5C could be released in 4.7-inch and 5.7-inch versions.
