Nokia is all set to unveil a cheaper Windows Phone device, the Lumia 610 and a global version of the LTE-enabled Lumia 900 at next week’s MWC, according to Reuters. Nokia had earlier launched the Lumia 900 with AT&T at CES this year. Earlier today, the Finnish handset giant also released a teaser video for what seems to be a high-end camera phone, probably the successor to the N8. Nokia is also expected to unveil at least a couple of phones in its affordable, mass market Asha series. Nokia is hosting a press conference on Monday, February 27.
