Looks like it is the Chinese manufacturer ZTE corp who might take a ‘bold’ step forward and might as well be the first to embrace the FireFox OS.
The Spec at a glance –
Qualcomm MSM7225A (45 nm, ARMv7, Up To 800 MHz, Adreno 205 ?)
3.5-inch HVGA TFT capacitive display
256MB DDR SDRAM
512MB NAND storage
3.2-megapixel front-facing (FF) cam – If this is true, then it would probably be the first smartphone, not to have a rear cam, but has a FF cam.
