More Apple iPhone 5S concepts surface, suggest 2 screen sizes

We came across a couple of iPhone designs which we haven't seen before. The first appears to be made out of plastic and closely resembles the popular iPod Touch. It will allegedly be the rumored cheaper new iPhone. It also appears to have a slightly smaller screen than the current 4" Retina on the iPhone 5.

The second device is the more interesting one and is slated as the iPhone 5S (or maybe even iPhone 6). It's larger than the current iPhone 5 and sports a bigger, almost bezel-less screen with sloping edges. It sports a rather strange-looking cyan color and the front appears to be entirely made of glass. The back, like on the smaller device, looks to be plastic as well.

The images aren't of the best quality so the material used on the concept phones could be something other than plastic, like glossy aluminum. The edges around the screen look to be precision cut - just like on the iPhone 5.

 
The two new iPhone concepts

We urge you to take these images with a pinch of salt as they can prove to be nothing more than clever renders. That being said, there is always the possibility that what we're seeing are prototypes that Apple's working on prior to launching the final hardware.

This is not the first time we've seen an alleged iPhone render-slash-concept and these are likely to start popping up even more with the summer just around the corner.
