> “We expect iPhones are similarly vulnerable, but we only tested our attack on Androids,” Peng Cheng, a doctoral student at Lancaster University told me in an email.

Well, of course not. First of all, iPhones don't have unlock patterns. Which greatly diminishes the usefulness of this approach. Also, I don't believe iOS would allow continuous use of microphone and speaker when the screen is off. And it is incredibly hard to sideload applications on unsuspecting users.
