It's called "matte green" and it's already available to order from AT&T's website.
The green variation of the device comes with Windows Phone 8.1 preinstalled, and is otherwise identical to the differently colored models that have been selling for quite a while.
To buy a green Lumia 1520, you need to pay $199.99 if you opt for a two-year contract, or $584.99 sans contract. If you use AT&T's Next installment plan, you don't pay anything outright but then have to make either 20 monthly payments of $29.25 or 24 monthly payments of $24.38, depending on which option you choose.
The Nokia Lumia 1520 has a 6-inch 1080p touchscreen, a 20 MP rear camera, a 1.2 MP front snapper, a Qualcomm Snapdragon 800 SoC with a 2.2 GHz quad-core CPU, 2GB of RAM, and a 3400 mAh battery. At this moment it's still unclear if the green hue will make its way to other countries.
What is wrong with this company. They don't even trying to enter bussines market niche. Those colors... oh dear..
Man the Nokia colors makes you wanna eat the phone looks like candy
The best Windows phone in fact MUST have micro SD expansion and with 5.5" Display and less than 9mm thickness. Nowadays, a phone with 5" display is too small and 6" display is too big for a phone. (in my own option)
