Windows Phone 8 (WP8) smartphones made their appearance in Q4 2012 and have gained decent popularity in the smartphone space. Nokia Lumia 920 and HTC 8X have been one of the most popular WP8-powered smartphones and both the smartphones are now available for free on a two-year contract.

The Microsoft Store is offering the AT&T versions of Lumia 920 and HTC 8X for free on a two-year contract or eligible upgrades. The Lumia 920 is available in black, red and yellow color options and the HTC 8X in yellow and blue colors. AT&T, on the other hand, is charging $99.99 for the Lumia 920 and $49.99 for HTC 8X.

Both the Lumia 920 and HTC 8X are flagship WP8 smartphones of their respective companies and include high-end features.

The Lumia 920 sports a 4.5-inch curved glass WXGA LCD display with 1280 x 768 pixels resolution at 332 pixels per inch. The smartphone packs in a 1.5 GHz dual-core Snapdragon S4 Processor and a 2000 mAh battery.

The Lumia 920 sports an 8.7-megapixel rear-facing camera with the much-touted PureView technology along with autofocus, dual LED flash and Carl Zeiss Tessar lens. The smartphone offers 32GB of on-board storage and no option to expand the memory using a microSD card. The device also supports wireless charging.

The HTC 8X has a 1.5GHz dual-core Snapdragon S4 processor and 1GB of RAM. The device has 16GB of internal storage; however, it has no microSD card slot option for expandable memory. A 1800 mAh battery boosts the device and the HTC 8X sports an 8-megapixel rear-facing camera with f/2.0 aperture and 28mm lens with a dedicated ImageChip for fast focus speed. The device also includes a 2.1-megapixel front-facing camera for video calling.

The HTC 8X is available in a variety of attractive colors and supports Near-Field Communications, Wi-Fi and Bluetooth.

Both the Lumia 920 and HTC 8X may seem worth the money if Microsoft Store does not ask for an upfront charge.
