Nokia may have introduced its first Windows Phone 8 handsets earlier this week, but there's more to come. We've already detailed a mid- to low-end "Zeal" Windows Phone 8 device, due to ship in early 2013, and now we're hearing from several sources that Nokia has another handset planned. A 4-inch "Flame" Windows Phone 8 device is said to include 512MB RAM, a 1.0GHz dual-core processor, 5-megapixel camera, and 4GB of storage.

Although the specs are fairly low, Flame owners will be able to upgrade the storage with an optional microSD card. The handset will likely be targeted at low-cost markets and offered at similar price points to the existing Lumia 610 and 710 devices. Availability isn't set in stone just yet, but we hear that the Flame will arrive within the first quarter of 2013.
