This recent press image leaked by evleaks seems to put the Nokia X name into concrete. The device was codenamed Normandy thus far and appears a low-end Android device bound for the Asha lineup next month.
The specs are expected to be a 4" WVGA display, dual-core 1 GHz Snapdragon chip (perhaps Snapdragon 200), 512 MB of RAM, 5 MP camera, dual-SIM support and a 1,500 mAh battery.
