So we know that Verizon will be getting their hands on the Nokia Lumia 928, or at least that’s what the leaked renders are suggesting, but what will AT&T get? We know that they have the Lumia 920, but we guess AT&T wouldn’t mind upstaging Verizon, especially with another high-end Lumia device, right? Well according to the rumors, it seems that a Nokia model RM-877 might be on track for a launch on AT&T’s network. As far as the specifications of the phone is concerned, not much else is known except that it could come with a HD display with a resolution of 1280×768. Considering that HD displays is currently the highest that Windows Phone devices are allowed to go up to for now, with Full HD 1080p support planned for the near future, we can only assume that this will be a higher-end Lumia device. We’ll keep a close eye on this for now so be sure to check back with us at a later date for the details.
