According to WPCentral, a series of recently leaked videos show that the AT&T sales representatives have been receiving training for the new Nokia device and are being introduced to the main features and unique selling points of the phone. The same videos also confirm that the network provider will have exclusive rights over the new Lumia smartphone for six months. Therefore, by May next year, other major network providers like Verizon, Sprint and T-Mobile will also receive their own versions of the Lumia 920 smartphone.

The videos, which were leaked to WPCentral by an anonymous AT&T source, offer a general overview of the phone, including its technical aspects and the Windows 8 OS. The videos talk about the phone's 4.5-inch 1280 x 768 PureMotion HD+ display, the latest Windows 8 operating system, 1.5GHz dual-core Snapdragon S4 CPU, and the 8-megapixel PureView rear camera. In one video, the Nokia City Lens app, which will come pre-installed on Nokia handsets has been highlighted, while another emphasizes the new phone's wireless charging feature along with other significant accessories like charging plate, the charging stand and the JBL PowerUp wireless speaker.

Meanwhile, the other Lumia 820 handset, which was released alongside the Lumia 920 will be running on AT&T, but T-Mobile and Verizon Wireless (VZ) will get the Lumia 810 and Lumia 822, respectively, the Finnish smartphone maker informed.
