Last month we saw the first leaks about the new wireless Polar heart monitor made for Nokia mobile phones. Well, now it’s official. And it comes in the company of Nokia N79 through a special retail combo.

The Polar WearLink Bluetooth heart rate belt allows you to monitor your heart rate while practicing so you can improve the way you train by staying focused on your training goals.

While you're training you can listen to the music stored on the 4 GB microSD card you'll find enclosed in the Nokia N79 Active pack. There will also be a pair of sports headphones and an armband which should make the Nokia N79 easier to wear while jogging.

At the same time you can monitor your heart rate using the handset, again, and see if you need to step up or if it's time for a little brake.

An updated version of the Nokia Sports Tracker application is expected to become available by the time the Nokia N79 Active hits the shelves (release time still unknown). The Sports Tracker allows keeping and sharing your workout records or favorite routes.

We still remember the first cooperation between the two Finn companies - Nokia and Polar. Back in 2004 they introduced the Polar S625X Running Computer and Polar S725 Cycling Monitor for Nokia 5140.

The Nokia N79 Active will only be available in select markets for an estimated price of 375 EUR before taxes and subsides.

The nice looking Petrol Black version of Nokia N79 appeared today on the Nokia UK store web page. It's available in a so-called Nokia N79 Eco pack. What makes it “Eco” is the lack of a charger. While that sounds like a strange lind of eco-friendly initiative, it actually isn't.

When there's no charger in the box the package can be much smaller. That means less paper and water wasted, fewer trucks for all Nokia products to be delivered worldwide needed and millions of euro saved (of course there's an economical side of the ecology). Plus re-using your older Nokia charger, saves some recycling expenses.

Nokia stated that in nearly two years they have sold 250 million phones in small packages (all lower to midrange ones) and saved 15 000 tones of packaging material, 100 000 cubic meters of water and avoided 5000 truck journeys as more phones fitted in each truck.

Check out those articles (here and there). They are quite a read.

In fact, there's something else and it is important, too. The sum of 4 GBP (around 4.5 euro or 6 USD) of the 319 GBP paid for every Nokia N79 Eco will be donated to the WWF.

The price of the eco-friendly N79 is not much different from that of the regular Nokia N79, but the extra cool Petrol Black color is pretty much worth it by our books plus there's a nice eco campaign involved. Who needs another charger anyway?

The Nokia N79 Eco is now available (for online pre-order, though).
