Sony Ericsson has launched two phones that flaunt a lot of green features. Sony Ericsson Elm and Sony Ericsson Hazel, are the updated versions of the previously known ‘Susan and Sunny’. These are the new greenheart phones by Sony Ericsson. The Elm is a candybar with a curved case, while the Hazel is a slider. The handsets are made of recycled plastic, and thus are have almost no hazardous chemicals. Also these come with e-manuals. The Hazel and Elm also feature a Walk Mate eco application, a green calculator and a low power consumption charger (called EP300 GreenHeart).
