"Let's meet at our place" is the greeting on Apple's invite to its fall event, which lands on September 12 this year. The presentation will be held in the newly constructed Steve Jobs Theater at Apple's new Cupertino headquarters. The theater was specifically designed to host Apple events, and what better way to christen the new space with what is expected to be a big iPhone debut.
