Who says tree-hugging has to be boring? Actually, Sony Ericsson's latest sets to join the eco-friendly GreenHeart
line aren't anything special, but at least they don't slouch in the specs department -- both the Hazel slider and Elm candybar announced today feature 5 megapixel cams, GPS with geotagging, LED flashes, and dual-band HSPA on top of quadband EDGE. The real news, though, might be the introduction of SE's very first GreenHeart accessory -- the VH700 stereo Bluetooth headset -- which ponies up dual mics for improved call quality and micro-USB recharging. It'll hit in the first quarter of the year along with the Elm; the Hazel follows on in the second quarter.
