Based upon information revealed yesterday, Apple is likely to release the iPhone 5S on September 27. The iPhone 5S will be a low cost iPhone, featuring a plastic casing. The plastic casing will allow Apple to offer the iPhone in a variety of colors, instead of just white and black.
If the videos (below) and photos (above) are correct, the design of the 5S is not that much different from the current iteration of the iPhone. The plastic edges are rounded somewhat, but the look and size are basically the same.
It is expected that the 5S will sport the new Apple OS.
A couple of released videos reportedly show off the new case.
