Nokia unveils the colorful Lumia 920, 820 (pictures)

After a short introduction by Nokia CEO Stephen Elop, Jo Harlow, executive vice president of smart devices at Nokia, kicks off the show holding a yellow Lumia 920.

In addition to the City Lens feature and the camera's image stabilization technology, the 920 will also have Nokia Maps with augmented reality -- an interactive live map experience.

Harlow said that the device's PureMotion HD+ display is the best smartphone display innovation. It includes blur-free scrolling, crisp images, sharper pictures, and videos "that pop."

The handset is powered by a 2,000mAh battery and a Qualcomm Snapdragon S4 processor.

The device will also have wireless charging capabilities. Here, it is set up on top of a "Fatboy charging pillow" that users will need to purchase in addition to the Lumia 920. Nokia has teamed up with Virgin Atlantic and The Coffee Bean & Tea Leaf to provide wireless charging stations.

Joe Belfiore, corporate vice president of Microsoft, demos the Windows Phone 8's start screen's new small tile option, as well as the personalized live tile for individuals.

By holding the power and home button, users can now take screenshots on the Lumia 920.

In addition to working seamlessly across multiple device platforms, WP8 comes packed with photo features like multiple lenses through the integrated FX Suite app.

Kevin Shields, senior vice president of Nokia, takes the stage to dive into the wireless charging features.

Not only can the Lumia 920 charge on a plate, but by using NFC, it can also work wirelessly with a slew of JBL audio products.

The device can sit up top a JBL Power Up speaker and play music while charging -- all without wires.

By tapping against a pair of JBL headphones, music can also play through the Lumia 920.

More camera features include a Smart Shot function that crops away unwanted objects.

A cinemagraph tool creates GIF-like images, similar to moving photos, in a snap.

The other WP8 Lumia device is the 820, a slightly smaller handset (it has a 4.3-inch screen, whereas the 920 has a 4.5-inch screen) with rounded corners and a removable back plate that comes in several colors and has wireless charging capabilities.
