If syncing your phone with a workout routine isn't your cup of tea, Nokia has unveiled another N79 variant, the Eco. For the same cost as the standard version, you'll get smaller packaging, a petrol black casing with dark gray / steel gray / deep plum covers, and no charger whatsoever. The company is hoping you'll reuse your old charger instead of throwing it out. As for the outdated phone that came with that adapter, we're sure they'd love you to send that back for spare parts. The Eco is now available for pre-order from Nokia UK, with £4 of each purchase going towards the World Wildlife Fund.
