Sony Ericsson made a commitment that it'd be using lessons learned from the development of its GreenHeart concept phone (pictured) in future production devices, and the first fruits of that labor should break this week. The company has announced that it'll be announcing handsets -- yes, plural -- on June 4 at 1:00PM UK time, which likely means that we can expect super-efficient packaging, chargers that waste little or no power, eco-plastic bodies, and electronic manuals, among other good feel-good technologies. Of course, it's all going to have to be awesome if we're going to buy into it, too -- green tech version of the Aino, anyone?
