There are still a handful of devices out there that Nokia plans to release before Microsoft officially acquires its devices and services unit.
One of those is expected to be the company's first Windows RT-based tablet, the Lumia 2520 (codename Sirius). FCC documents reveal that the agency has approved a Nokia tablet PC, widely assumed to be the 2520, Engadget reported. The information reveals that it will be supported by AT&T's, Verizon's and T-Mobile's networks.
Look for the 2520 to sport a 10.1-inch touchscreen (same as a traditional Apple iPad) and a powerful 2.15 GHz processor.
The 2520 is one of as many of six devices that Nokia is expected to unveil at an upcoming event in Abu Dhabi on Oct. 22. Others might include the new Lumia 1520 smartphone and another exclusive for Verizon, the 929.
