These show the handsets running NTT DoCoMo firmware but without the hard branding on the handset. Instead of the NTT DoCoMo logo at the top of the handset, you can instead see an Xperia logo with the Sony logo on the bottom. The reason why Sony logo remains at the bottom most probably relates to the fact that it is engineered to glow at the bottom. There’s still no official word on when we may see this in the west, but judging by previous leaks it will probably launch from September.
