there are not many details on Samsungs proposed Blue Earth handset, a seriously environmentally friendly green phone. Made from PCM, a recycled plastic from water bottles, the phone boast an "eco" mode for efficiently adjusting screen brightness, backlight duration and Bluetooth usage, and an "eco walk" app / built-in pedometer to tell you how much CO2 emission you've saved by walking instead of driving. It's got a giant solar panel on the back that'll apparently charge it enough to make a phone call anytime theres direct sunlight. It'll come in recycled packaging with an energy efficient charger. No word on the OS or hardware specs, also not a word on price yet, but environmentalists can look forward to this one second half of this year.
