Apple started prepping for its highly-anticipated iPhone event last week, hanging colorful banners outside of the Yerba Buena Center for the Arts in San Francisco.

The company’s venue decorations are typically more interesting than they are insightful. But this time, they may contain clues to its upcoming announcement…

MacRumors passes along a discovery from a reader that the colorful streaks in Apple’s adornments are made up of stretched iOS icons: Game Center, iTunes and Music.

As you can imagine, speculation has ensued that this indicates Apple will be unveiling an iPhone with a “stretched” screen next week. The rumor mill has been calling for a larger 4-inch iPhone display for months, pointing to reports and leaked parts for confirmation.

If that consensus holds true, the new iPhone will feature a taller, but not wider, 4-inch Retina display with a resolution of 1136 x 640 and a ratio close to 16 x 9.

Banners or not, we are fully expecting to see an iPhone with a bigger display and a number of other changes next week. But we have to admit it was a pretty interesting  find.

What do you think?
