9to5Mac has recently received some pictures of the Yerba Buena center showing that Apple is preparing for the september 12th event. In these images you can see the Apple logos are up. We have also heard word that the banners which usually highlight the key points of the event will be put up later today or tomorrow. If someone can get pictures of these then we may have a good idea what the new iPhone looks like.

Check out the images below:
