Apart from dual-cameras & Boomsound that evleaks claimed it will come with, seems it will launch with support for VoLTE, if Engadget’s sources have to be believed. This makes us believe it will run Windows Phone 8.1 GDR1 out of box. That will not be surprising considering the fact that Windows Phone 8.1 GDR1 has RTMed already and OEMs are testing it.
