cell phones with optical zooming?

According to an article I read recently
(http://www.newscientisttech.com/article/mg19125636.200), "adaptable
liquid lenses are already used in devices such as cellphones."

If that's true, then shouldn't cell phone cameras have optical zoom
capability?

I believe that optical zooming requires 3 or more lenses, not to mention a
method(motor or knob/lever for moving at least 2 of them. That would
require a lot more room than users would want to put up with. A single
adjustable (liquid?) lens would only adjust focus.

IMHO
