Nokia is planning to launch the Lumia 900 Ace (codenamed Eloko) at the 2012 Consumer Electronics Show next week in Las Vegas. Specifications and images have leaked out ahead of the introduction that paints a pretty good picture as to what we can expect from Nokia's flagship Windows Phone.

For starters, the handset will feature a 1.4GHz processor, a 4.3-inch WVGA Nokia ClearBlack AMOLED display, 512MB of RAM and an 8MP rear-facing camera. At 4.3-inches, the screen is a bit larger than the 3.7-inch display found on the Lumia 800 but the resolution remains the same. The phone is said to ship with the Mango build of Windows Phone and includes an 1830mAh battery. 

PocketNow is pretty certain that the device will be sold carrier locked but that it will contain the 1700MHz band required to work on T-Mobile's 3G network. This means that a workaround to run the 900 via T-Mobile will likely surface soon after launch.

The Ace weighs in at 160 grams, just 18 grams more than the Lumia 800 which is likely due to the larger screen and the addition of an LTE radio. Thickness is expected to be around 12 millimeters.

There's no mention of pricing for Nokia's high-end Lumia phone but we should know more next week at CES. In addition to the 900, Nokia is rumored to be preparing another mid-range device for launch as well, the Lumia 719. The 900 Ace is set to launch with AT&T and we suspect the 719 would follow the same path.
