The last leaked T-Mobile roadmap we got to look at spelled out what the carrier was planning to release through the very start of April. Now a new document has arrived that gives us a glimpse into what to expect just a few more weeks further out, and reveals what could be a new Nokia Windows Phone model for late April, codenamed Flame.

Supposedly, the carrier will be introducing this Nokia Flame on April 24. It turns out that the name Flame has been tied to Nokia rumors before, when last September the model was claimed to be an upcoming lower-end Windows Phone 8 handset with a 1GHz dual-core SoC, 512MB of RAM, a four-inch display (no word on resolution, but presumably WVGA), 4GB of flash memory (supporting microSD expansion), and a five-megapixel main camera.

At the time, the Flame was tipped for release in early 2013, so this April date sounds pretty much in line with that. Of course, we expect the phone to get a proper Lumia number before launch.

Could the forthcoming arrival of this handset be why T-Mobile is neglecting to deliver Windows Phone 7.8 for the Lumia 710?
