Sony Ericsson recently announced the addition of the GreenHeart phones to their list of models.
The new models are just slightly upgraded versions of the C901 and Naite models. The new features include a 15 percent smaller carbon footprint, an online-only manual to save paper, less packaging and the phones are made of at least 50 percent recycled plastics. Sony Ericsson is essentially using the the new models to introduce these green features before applying them to their entire portfolio.
