80 percent recycled materials might be considered pretty environmentally friendly, but a cellphone with a built-in solar panel? Now that's something with the potential to make Al Gore cry. Enter the Samsung E11077. It's solar panel-equipped back cover comes in at 1.2-mm thin, and is said to revive a dead battery after just 15 minutes in the sun. Besides the FM radio and flashlight features, the only other noteworthy addition is an "Eco" profile, that essentially just changes screen brightness and shuts the Bluetooth off. If you're interested, the cost of entry is a reasonable $59, but you'll probably have to find an importer, as we don't expect this tree hugger to land stateside any time soon.
