We're just days away from Nokia's Mobile World Congress event and we're starting to see the first signs of new Lumias. Earlier today Lumia 720 and 520 images leaked, but now a new device has passed through FCC checks. Named as the RM-860, we understand this is Nokia's Laser device for Verizon. The FCC lists LTE bands 4 and 13, inline with the required support for Verizon.

The team over at AdDuplex, who provide ads for Windows Phone apps, revealed to The Verge today that it has spotted instances of the RM-860 being tested on Verizon through its logs recently. AdDuplex says the device has the same screen resolution as the Lumia 920 (1280x768), one that's particularly unique for Windows Phone 8 devices. We're told that Nokia's Laser will have similar, if not identical, hardware specifications to the Lumia 920.

We don't know a whole lot else about Nokia's Laser device, but we understand the handset will debut in the coming months on Verizon as a flagship device. Microsoft is said to be investing marketing dollars to push the Laser when it debuts. It's not likely that we'll see this unveiled at Mobile World Congress, but expect to see it by June.
