Nokia has officially unveiled its new flagship smartphone, the Lumia 920. As expected, Nokia's new Lumia has received a bump in specs over the previous iteration, with a 1.5GHz Qualcomm Snapdragon S4 dual core processor, a slightly larger 4.5-inch curved glass display with a 768 x 1280 resolution, a 2,000mAh battery, and the new Windows Phone 8 operating system. Nokia is calling its new display the "PureMotion HD+," and says that it's the "best smartphone display innovation" the company has ever made, with "better than HD resolution" and fast refresh rates — Nokia says it's the "brightest smartphone HD display ever," and also the "fastest LCD display ever shipped on a smartphone." Nokia is also touting the PureMotion HD+'s daylight viewing capabilities, and says that the phone's color tone and brightness automatically responds to sunlight.

Nokia says the new Lumia will come in "vibrant colors" (the yellow, red, white, grey, and black pictured above), and features a one-piece polycarbonate body. As expected, Nokia is also pulling a couple of tricks out of its sleeve: it's adding wireless charging for the Lumia 920, built on the Qi wireless power standard. Nokia is also incorporating its "PureView" camera technology, but just don't get too excited: we're looking at an 8.7 megapixel sensor in the 920, not the 41 megapixels in the PureView 808. Nokia says the 920 features a "floating lens" optical image stabilization system that allows for sharper photographs in low-light situations, a better app and camera interface, and 1080p video recording.

CEO Stephen Elop declined to give specific pricing or release dates, but he did say that Nokia would be entering "select markets" with "intense focus" in Q4 of 2012.
