We’ve just spent some time with Samsung’s brand new eco-friendly device, the Samsung Replenish. In terms of eco-friendliness, the device is made of up over 80% recyclable materials. It features a 2-megapixel camera, 2.8-inch display, reasonably large 1600 mAh battery and it runs Android 2.2 (Froyo). The QWERTY keyboard is reasonably decent, too. We’re able to pound out emails quickly, and it’s reminiscent of the old Samsung Blackjack-style layout. The big news here is that there’s an optional solar-charging battery cover that will give you an extra 20 minutes of talk time after 1 hour of sun bathing. Sprint is also encouraging and rewarding Replenish owners for being so green by not charging the extra $10 smartphone fee that’s normally required. The Samsung Replenish will be available on May 8th for $49.99 with color choices of black, blue or magenta.
