To your question about cell phones and personal learning, Wikipedia Zero isn’t open education specifically, but it is a model of what is possible
Wikipedia Zero. This team partners with mobile carriers throughout the world to provide zero-rated Wikipedia (free of data charges) in developing areas.
So far we’ve launched Wikipedia Zero in 59 countries with 67 operators. We estimate that more than 400 million people can now access Wikipedia free of data charges. Our goal is to work with every mobile operator on the planet — email us at firstname.lastname@example.org
WikiEducator is based on Media Wiki, so it should be possible to expand into open education relatively easily using similar functional provided by Wikipedia Zero.
