Nokia, Microsoft and AT&T have finally taken the wraps off the Nokia Lumia 900. The smartphone will be exclusively available via AT&T “in the coming months,” in matte black and cyan.

No word on the pricing yet, but Nokia’s CEO Stephen Elop mentioned that the company plans to “enter aggressively” on the North American market, which might indicate that the Finnish handset maker is willing to price its products cheaper than before.

The third Nokia handset to run Windows Phone operating system, Nokia Lumia 900 is the first to comes with LTE support. The smartphone allows data downloads up to 50Mbps on AT&T’s 4G LTE network, or HSPA downloads up to 21Mbps.

Nokia Lumia 900 sports a brilliant 4.3-inch AMOLED capacitive touchscreen display with 800 x 480 pixels resolution, which is based on Nokia’s ClearBlack technology.

The phone boasts an impressive 8-megapixel rear camera with exclusive Carl Zeiss optics that features a large aperture (F2.2) and wide angle focal length (28mm). Furthermore, the smartphone packs a 1-megapixel front-facing camera for video calling.

The phone’s high capacity 1830 mAH battery is rated by the manufacturer for up to 300 hours of standby time or up to 7 hours of talk time.

On the inside, the Lumia 900 is equipped with a 1.4 GHz single core Qualcomm Snapdragon APQ8055 processor, as well as 16GB (14GB user available) of internal memory and 512MB of RAM. Additional storage is available via SkyDrive cloud storage.

The Lumia 900 runs Microsoft’s Windows Phone 7.5 Mango Commercial Release 2 (Mango + LTE) and comes pre-installed with several AT&T and Nokia services and apps, such as U-verse Mobile, Nokia Drive, ESPN sports hub, CNN App, and Univision App.

According to Nokia, the device, along with the rest of Lumia series smartphones, will get around 20 EA popular games in the near future.

It’s been almost 3 years since Symbian S60 5th Edition, now known as Symbian^1, made its way onto the mobile phone market, but the platform hasn’t changed too much in the meantime.

However, Nokia is still one the largest handset manufacturers in the world and its devices continue to sell very well, despite the fact that the company hasn’t come up with anything completely innovative in the last few years.

While Symbian^1 remains the main mobile platform for Nokia’s low- and mid-entry smartphones, Symbian^3 has been pushed forward by the Finnish manufacturer in an attempt to reduce the technological gap between itself and its rivals.

Nokia C5-03 seems to be placed on the ‘red thin line’ in this fight between giants such as Apple, Google, Motorola, Samsung and HTC.

Even though the device shows potential when it comes to hardware, it really is the victim of a rather obsolete operating system, Symbian^1.

Announced in October 2010, Nokia C5-03 was launched on the market in December 2010 and can be bought for about 200 US dollars without a subscription. Potential customers can choose from four available color schemes: Graphite Black, Lime Green, Petrol Blue and Aluminum Grey.

The first thing you notice about the C5-03 is the compactness of the device, as well as the minimalistic look. It is dubbed as an eco-friendly mobile phone, as 80% of the handset’s body is recyclable. Nokia C5-03 is neither a music phone, nor a business device, but it can be used as both with some success.
However, Nokia made a few compromises when it designed the C5-03, as the phone lacks a dedicated camera shutter, LED flash and music keys. Still, you are left with a generous 3.2-inch touch screen, which seems larger because the bezel has been reduced to a minimum. The handset measures 105.8 x 51 x 13.8 mm and weighs 93g

Above the screen is the usual earpiece, but there’s no proximity sensor, which is one of the downsides of the phone. Below the display there’s a long plastic stripe that includes the standard Accept/End calls buttons, as well as the Menu key.
The left side of the phone is totally barren, while on the right side there’s a dual-volume key, as well as the lock/unlock key, which is now clickable button instead of a sliding one. The charger port has been moved to the bottom of the phone, while the 3.5mm audio jack and the microUSB ports have been placed at the top. None of them have plastic covers, so dirt might be a problem later on.

The back cover of the phone is made from a shiny plastic that looks stylish and expensive, but in fact is 100% recyclable. The 5-megapixel camera on the back lacks LED flash and autofocus. At the base of the back cover there’s a small loudspeaker. The microSD card slot can be found as soon as the back cover is removed, on the right side of the phone.
