Based on an unremarkable and fairly inexpensive handset launched earlier this year, the 3110 Evolve is a basic tri-band GSM phone with a 128 x 160 pixel display, 1.3 megapixel camera, FM stereo radio, microSD expandable memory and an MP3 player, plus Bluetooth and USB connectivity.

It's a pretty lightweight handset at 87 grams, but you can tell by the specification that the screen is the 3110 Evolve's biggest weakness.

So what makes this different from a standard 3110? Well, Nokia say that there is "bio-sourced material on the covers", and they also say that the cover material is 50% renewable - so we guess that it uses some sort of plant-based hydrocarbon compound rather than plastic from fossil fuels. The Nokia 3110 Evolve comes in a much smaller sales package consisting of 60% recycled content, and there's a new more efficient phone charger. Nokia say that the charger uses "94% less energy than the Energy Star requirements" but does not give any figures comparing it to a standard unit.

We think that there is a fatal flaw in Nokia's thinking - the Nokia 3110 Evolve is not the sort of phone that you'll want to hang onto for a few years. The limitations of the low-resolution screen will probably drive many people to replace it quite early. Our advice is this - buy a better phone, and keep it for longer. Then when you've finished with it, recycle it and raise some money for a worthwhile charity. Oh, and unplugging your phone charger when not in use is a good thing too.

The Nokia 3110 Evolve should be available during Q1 2008. No pricing was available at the time of going to press.
