A mystery Nokia Lumia device, labeled RM-860, just appeared over at the FCC website with support for Verizon Wireless. This could be the Nokia Lumia 920 variant for the largest 4G LTE network in the United States. We might be hearing more about this device at the Nokia press conference in Mobile World Congress.

New Verizon Nokia phone (RM-860) has a 1280×768 resolution. Meaning it’s either a Lumia 920 variant or a new high-end model. #MWC13

Engadget reports that the device supports LTE bands 4 and 13, the telltale marks of a Verizon smartphone. Alan Mendelevich from Adduplex also noted that the mystery Lumia device features a 1280×768 resolution. That’s the same screen resolution found on the Nokia Lumia 920. We don’t know anything else about this device, but all could be revealed on Monday.

Verizon Wireless currently offers the Nokia Lumia 822. Nokia fans on Verizon waiting for a higher-end Lumia now have something to look forward to.
