According to the Maximum PC article on this:
"The unidentified source claims Apple owns a patent on "controlling software using buttons connected by a standard 3.5mm headphone jack (at least for music and video playback controls), and would not grant Google a license to the patent."
So I don't think it was HAVING a 3.5mm headphone jack, it was related to controlling the phone via the 3.5mm headphone cable...? Kind of bizarre.
