FCC just approved a T-Mobile version of the Grand X ZTE. The Grand X has a 4.3-inch IPS LCD display with qHD (960×540 pixel) resolution and a 5-megapixel camera, 3G bands and offers a 1.0 GHz dual core processor. Also has a memory card slot and removable battery.
S0 far T-Mobile or either ZTE announced this phone. Maybe we will see it on the new CES.
