Samsung Blue Earth Cellphone has Built-in Solar Charger

Green-conscious Europe to get phone later this year

The phone's front is a touchscreen

Another twist from Samsung: The back of the touchscreen Blue Earth phone is covered with a solar panel. It's another approach to getting power without plugging in. Like the upcoming Powcell sleeves for the iPhone and BlackBerry Curve, the panel is meant for topping off a battery.

The phone's eco cred includes being made from recycled plastic from water bottles. It's scheduled for release in green-conscious Europe later this year.
