Apple Inc. (AAPL) sent out invitations to a Sept. 12 product event in San Francisco, where the company is expected to unveil a redesigned iPhone. “It’s almost here,” Cupertino, California-based Apple said in the invitation, whose image includes a ‘5’ in shadow, possibly in reference to the new product’s name. At the event, set for 10 a.m. at Yerba Buena Center for the Arts, Apple will introduce a new iPhone with a larger screen and thinner body, two people with knowledge of the plans said in July.
