The image above shows what is apparently iOS 6 running through a simulator app. It’s being scaled up to 640×1136, which is the reported resolution of the upcoming iPhone. Most interesting, is the fact that it allows for an extra row of app icons. For instance, current versions of iOS for iPhone show four rows of icons. However, the version of iOS 6 shown above has that fifth row.
If anything, this is yet another indication that the next iPhone will have the taller form-factor.
We will find out for sure when the next iPhone is announced and released. If rumors and reports are accurate, we can expect something on September 12.
