Nokia launched its flagship smartphone, Nokia Lumia 800. The Finnish cellphone giant unveiled the Nokia Lumia 800 and to compete with Apple's iPhone 4S, Samsung-Google's Galaxy Nexus, and Motorola's Droid RAZR in the smartphones battle.

Here are some of the things that you need to know about the Nokia's new Windows phone:

1. State-of-the-art design

If there is one thing that can be compared between Nokia and Apple, it is the industrial design of their handsets. Apple goes for sleek, stylish and sophisticated minimalist design and sticking to black and white colors. Nokia, on the other hand, goes for stylish and sophisticated design matched with exciting and trendy colors. The new Lumia 800 is available in cyan, magenta and black.

In the Lumia 800, the polycarbonated shells are not simply sprayed with paint; but the whole material is dyed so that the phone will still maintain its color even if it is scratched. Moreover, Nokia meticulously tested various creams and lotions to ensure that the handset will not acquire any stain.

The Lumia 800 borrowed the design of the Nokia N9 equipped with a camera button and Mango (Windows Phone 7.5) mobile operating system.

2. Screen display

The Lumia 800 sports a 3.7-inch AMOLED ClearBlack screen with 800x480 pixel resolution and a curve design. It may be incomparable with Apple's 720x1020 pixel resolution. The blacks were black and the colors are vibrant.

3. Camera

The Lumia 800 is equipped with 8-megapixel camera with a f/2.2 Carl Zeiss lens and 720p video capture at 30 frames-per-second. Most smartphones have 8-megapixel but the Carl Zeiss optics gained good reviews in other Nokia phones handsets.

4. Mango (Windows Phone 7.5) mobile OS

To Microsoft's credit, on the software side, the Lumia 800 seemed just as quick and responsive as any other phone running Mango. Microsoft is still in the early stages with Windows Phone. The full push to Mango took place earlier this month and users are giving it solid marks.

Microsoft has done something really special on the software side that allows users to pin certain functions of an application - like just the voice reminder function of Evernote - to a home screen. In short, the software that Microsoft has been building is great. What the company has needed, however, is flagship hardware.

As nice as some of the other Windows Phones are - and they are nice - nothing before the Lumia 800 really stood out against the smartphone competition. That's changed.

5. Other perks

The Nokia Lumia 800 is lightweight weighing only 5 ounces. The new smartphone is packing a single-core 1.4 GHz Qualcomm Snapdragon processor, 512 MB RAM, 16GB onboard storage, 802.11 b/g/n Wi-Fi and Bluetooth 2.1 connectivity, micro-USB port. Nokia claims the handset has up to 9.5 hours of talk time and up to 55 hours of music playback.

Nokia Lumia 800 is set to cost $580 off contract. A handset under a contract may be cheaper. Nokia Lumia 800 will be available next month in countries such as Germany, UK, Italy, Spain and France. The handset will be available in the US early 2012.
