Depressed about greenhouse gases? Check out NTT DoCoMo's Eco-Friendly phone, the FOMA N701i ECO. The Foma N701iECO uses mainly Kenaf fiber in the body material instead of ABS resin. Kenaf is a biodegradable, environmentally-friendly crop that has been researched by the United States Department of Agriculture for over 50 years. Weighing in at 115 grams, the phone has a 2.3-inch TFT color screen and uses a miniSD card to expand memory. Mostly the same as the N701i model.
