With the next-generation iPhone set to launch sometime in the next few months - many credible rumors suggest October - concepts of what the device could possibly look like are being produced by designers already. ADR Studio, a common source of such art has outed yet another concept mockup of what they call the "iPhone Plus". It depicts an extremely thin iPhone with a 4.3" screen and an aluminum back, similar to the iPad, or even the first-generation iPhone in some regards.
