CTIA 2008 in Las Vegas brought a lot of cool product introductions, including the highly touted Samsung Instinct, which is following in the footsteps of the Helio Ocean ($174) being touted as the "iPhone Killer."

But, I have to say that my favorite device of the entire show, was the Nokia Remade ? a purely concept device that doesn't make a single call or even send texts. Announced at the end of last year, the Remade is a slight yellow and silver clamshell that is made entirely of recycled cans and tires. In fact, inside out, the handset is made from previously used parts.

For a working Nokia model that's a little greener, check out the 3110 Evolve, the company's tri-band GSM device that is made with bio-covers from more than 50% renewable material. Even the device packaging is made of 60% recycled content and comes with Nokia's most energy efficient charger that uses 94% less energy than the Energy Star requirements according to the company.

Aside from the eco-factor, however, the Evolve, a revamp of the 3110 candy bar style handset, is fairly basic but solid. It comes with Bluetooth, a 1.3 megapixel camera, music player, built in FM radio, expandable memory and gets approximately 4 hours of talk time.
