In case you forgot, September is a very busy month when it comes to announcements in the mobile universe, with companies including Nokia, Motorola, Amazon, Apple and HTC having each scheduled its own media event at some point in early- to mid-September.

Nokia kicked off things today, unveiling two new Windows Phone handsets, the Lumia 920 and the Lumia 820, that are to fight existing and future Android and iOS handsets. Moreover, these two Lumia-branded smartphones are both running Windows Phone 8, Microsoft’s latest mobile OS.

Nokia Lumia 920

The Nokia Lumia 920 is obviously the new flagship device of the company, a handset labeled “the most innovative Lumia” by the Finnish handset maker. The device will offer users a few interesting features such as PureView camera and wireless charging, among other things.

Here are its main specs and features:

• Size: 130.3 x 70.8 x 10.7 mm
• Weight: 185g
• 4.5-inch PureMotion HD+ display with 1280 x 768 resolution, 332 PPI, 15:9 aspect ratio and Corning Gorilla Glass
• 1.5GHz Dual core Qualcomm Snapdragon S4 processor
• 1GB of RAM
• 32GB of built-in memory plus 7GB storage in SkyDrive
• 8.7-megapixel PureView camera with dual LED flash, Carl Zeiss Tessar lens, auto focus and full HD (1920 x 1080) video recording at 30fps
• 1280 x 960 front-facing camera with 720p HD (1280 x 720) video recording
• HSPA+ and LTE support
• A-GPS and Glonass support with Nokia Maps, Nokia Drive, Nokia City Lens, Nokia Transport, Offline maps, turn-by-turn voice navigation
• Bluetooth 3.1
• Wi-Fi and Mobile Hotspot support for up to 5 devices
• NFC
• Micro USB 2.0
• 2,000mAh battery
• Windows Phone 8 with Microsoft Office application and SkyDrive pre-installed
• Enterprise security features
• Nokia Music store

The specs of the Nokia Lumia 920 put it on par with current Android flagship devices, while some of its extra features and pre-loaded navigation and music apps will help the company distinguish its WP8 product from the crowd – other companies will also have WP8 handsets in stores, including Samsung and HTC.

In case the high-end Lumia model announced today is not for you, then here’s what you can expect from the second model, the Lumia 820.

The Nokia Lumia 820 is a bit smaller than the Lumia 920, sporting only a 4.3-inch display. But inside you’ll find plenty of similar specs and features, which make the device also a flagship device, rather than a mid-ranged WP8 creation – albeit the PureView camera and wireless charging features are not available on this device.

Here are the most important features of the Nokia Lumia 820:

• Size: 123.8 x 68.5 x 9.9 mm
• Weight: 160g
• 4.3-inch AMOLED ClearBlack display with 800 x 480 resolution and 15:9 aspect ratio
• 1.5GHz Dual core Qualcomm Snapdragon S4 processor
• 1GB of RAM
• 8GB of built-in memory plus 7GB storage in SkyDrive
• up to 32GB memory upgrade
• 8.0-megapixel camera with dual LED flash, Carl Zeiss Tessar lens, auto focus and full HD (1920 x 1080) video recording at 30fps
• 640 x 480 front-facing camera with VGA (640 x 480) video recording
• HSPA+ and LTE support
• A-GPS and Glonass support with Nokia Maps, Nokia Drive, Nokia City Lens, Nokia Transport, Offline maps, turn-by-turn voice navigation
• Bluetooth 3.1
• Wi-Fi and Mobile Hotspot support for up to 5 devices
• NFC
• Micro USB 2.0
• 1,650mAh battery
• Windows Phone 8 with Microsoft Office application and SkyDrive pre-installed

Pricing details and release dates

Both devices will be available in a variety of colors, but we have no idea when the two devices will hit stores and how much they will cost. Nokia’s CEO Stephen Elop did say that the Lumia 920 will be available in selected markets by the end of the year, without actually mentioning what countries will get it first, and whether the U.S. is included.

So, anyone enchanged by these new Nokia handsets? Ready to buy one for yourself first chance you get or are you sticking it out with Android?
