Despite the rumors stating that the T1 would have a metal body, it instead has a matte black plastic back with a circular raised camera in the top left hand corner, which is very reminiscent of the Nexus 7 and Nexus 5. Similarly, the big Nexus logo is placed sideways in the middle.
The device has already been known to have a 4:3 aspect ratio display. This image further shows the squarish shape of the device.
The HTC T1 is due to be launched this month so hopefully we are able to find out more about it soon.
