I saw a YouTube video on TechBlog of what they claim is the Sony Ericsson Z1 (Sony PlayStation Phone). The video is shaky and there is no way of course we can be sure. On the other hand my judgement at this moment is based on the other YouTube video below uploaded hours ago which I think is the real thing because of the quality of the video taken. Watch the video below.
Apparently the device has well rounded corners and four hard key buttons below the 4 inch touch screen, and the surface of the joypad is exactly as previously leaked.
