T-Mobile UK already has Sony's Xperia Z1 flagship, but its US-based counterpart is still to get it. Leaks of the US version of the Z1 continue with both the front and the back view of the device. The back is branded with the carrier logo, while the front shows the Sony-customized Android 4.2 build and the 4G connectivity icon.
There are a couple of differences between this unit and the official Xperia Z1 units we've seen already. Namely, the 3.5mm audio jack has moved and the front-facing camera is on the other side of the Sony logo. There also seems to be a new mic hole on the back. Neither the jack nor the front-facing camera match leaked shots of the Xperia Z1S.
