Hello .. I'm in dubai for a mobile show and I saw a white Nexus 4 on Quallcomm booth, and it looks amazing .. The white area around the back glass have some metallic touch and looks great .. Here's some pictures I took for the device .. These photos taken by my smartphone, I can drop by a DSLR and take better photos tomorrow ..
Update: It got the same specs as Black Nexus 4 .. 16 GB, Android 4.2 and No LTE, I guess there's no need to post the DSLR photos ..
