To celebrate the launch of the iPhone Duo this Friday, Apple has set up oversized iPhone Duo promotional displays at Apple Fifth Avenue in New York City, Apple Covent Garden in London, Apple BKC in India, and Apple Jing'an in Shanghai. The installations were already spotted under wraps, and Apple CEO John Ternus has since revealed what they look like in a photo of Apple Jing'an shared on his Weibo account today.
