The new mockups, posted by 9to5mac, show an iPhone sporting the same aspect ratio as the one on the iPhone 4S, but a larger 4-inch screen device.
The first three mockups come from design student Daniel Bautista. The concept appears to have a stretched screen and less bezel.
The other image is from apfelpage.de, a German site that imagined a slimmer, curvier iPhone 5.
In addition, the device has an edge-to-edge display and the volume buttons appear to be in line with the case.
This last concept is particularly interesting thanks to the positioning of the widgets in the iOS 6-powered iDevice.
