As expected, Nokia has just announced the Lumia 820, a mid-range Windows Phone 8 smartphone. The 820 is powered by the same 1.5GHz dual-core Snapdragon S4 and 1GB of RAM as the flagship Lumia 920, but will arrive with a smaller 4.3-inch WVGA OLED display, only 8GB of internal storage, and an eight-megapixel rear camera. The 8GB internal storage can be expanded via Windows Phone 8's extended microSD functionality.

Both the Lumia 820 and the flagship 920 include Syanptics technology called Super Sensitive Touch that enables them to detect touch through gloves or fingernails in additional to traditional capacitive input. Nokia is introducing exchangeable covers for the Lumia 820, available in a range of hues, including yellow, cyan, purple, red, grey, white, and black. It'll also sell covers that enable NFC, as well as wireless charging through its new range of charging accessories or any Qi-compatible hardware. As the covers are removable, so is the 820's 1650mAh battery.

Nokia says that the Lumia 820 will support LTE at launch, but won't detail which bands it'll support until it's ready to announce launch carriers. We'd previously heard the phone will be available through AT&T and T-Mobile, but Nokia has only stated that the 820 will be available in "select markets" in Q4. Check out our hands-on preview for some first impressions of the device.
