The outside of San Francisco's Yerba Buena Center for the Arts, where the 12 September event will take place, has been decorated with a colourful Apple banner to mark the occasion.

After closer inspection, a MacRumors forum member pointed out that the seemingly random colours in the banner might actually be stretched iOS icons.
MacRumors and its forum members went on to skew and shrink a photograph of Apple's banner to reveal that the forum member's claims appear to be correct, as you can see from the image below.
Pretty cool, right? So what does this mean?
Cult of Mac suggests that Apple is hinting at the rumoured 4in display that is expected to be introduced with the iPhone 5 on Wednesday. “Why would said icons be stretched,” the website asks. “Because the iPhone 5 is expected to feature a taller, thinner 4in display with a 16:9 aspect ratio.”
