The photos from Australian blogger Sonny Dickson show front and back views of two dummy handsets purportedly based on Apple's next-gen iPhone designs, possibly offering an early look into how the two variants stack up.
It should be noted that the dummy models were likely created for iPhone case manufacturers and may not portray the exact look of the final model. As such, the following breakdown is offered only for purposes of discussion.
As seen above, the larger 5.5-inch "iPhone 6" dummy model is essentially a upsized version of the 4.7-inch variations that have been floating around for months and carries over the iPad mini-esque design language of deeply rounded edges.
The introduction of rounded edges lends a softer appearance to the hardware and is a departure from Apple's current iPhone 5 and iPhone 5s handsets, which feature sharp angles and rounded corners. If the mockups are correct, Apple looks to be moving toward a more cohesive design language across its iOS device lineup, including the iPad Air and iPad mini.
A quick look at the aspect ratios of both screens reveals a near perfect match between the alleged 4.7-inch and 5.5-inch versions. This would be in line with Apple's standard operating procedure of offering hardware that ensures easy upscaling for app developers.
Aside from the apparent screen size boost and usual camera, Touch ID and speaker positioning, not much else can be gleaned from the front view of the mockups.
On the back, the larger version appears to sport an updated rear camera flash design with only one circular opening for the LED module. Unlike the iPhone 5s, which introduced Apple's dual-LED TrueTone flash installed behind a pill-shaped cutout, the updated single hole design possibly suggests the company was able to integrate the technology into a smaller package.
Most recently, a number of images showing an alleged iPhone 6 rear casing have been making the rounds. The part purported back panel features a cut-out Apple logo that could potentially be filled with a radio-transparent insert for increased wireless reception. That particular design was first employed in the second-generation iPad mini.
