Remember the giant ‘Retina’ in Apple’s huge event banner for the third-gen iPad? If you thought that was a subtle hint, then get ready, cause it’s even better this time around. We showed you the colorful signage Apple put up at the Yerba Buena Center over the weekend, and it sadly looked like there were no immediate iPhone 5 hints in the banner’s design. Think again.

Believe it or not, the banner currently hanging from Yerba Buena in San Francisco points to the rumored 4-inch display for the iPhone 5.

On Friday Apple started preparing the Yerba Buena Center in San Francisco, California for the long-awaited iPhone 5 event that will be taking place this Wednesday. Journalists will pile into the venue to watch Tim Cook and company unveil the next iPhone and other surprises. Per tradition, Apple has begun putting up larger banners outside of Yerba Buena the weekend before the event.

We stopped by Yerba Buena to get a look at the signage Apple is putting up. Check out more on-location shots from Yerba Buena in our gallery below.

Apple has begun prepping the Yerba Buena Center in San Francisco for the iPhone 5’s grand unveiling on September 12. Now that the Cupertino company has sent out invitations for the much-anticipated event, it has started decorating the venue with its logo, while exterior banners are expected to go up later today.

We decided to visit the Yerba Buena Center for the Arts in San Francisco to get a peek at the signage Apple is currently putting up for its iPad event next week. The colorful look and feel reminds us of the original iPad launch back in 2010.

Apple is set to announce its much-anticipated iPad 3 during the first week of March, according to sources for All Things D. It’s unclear when the device will actually launch, but it is said be “pretty much what we’ve been led to expect by the innumerable reports leading up to its release.”
