New pictures of a Sony Ericsson Xperia running Windows Phone have popped up again. The last bunch of pictures from a few days ago looked like they were from the same photo shoot back in March 2011, however the pictures below are from a completely separate time. How recently they were taken though is questionable.
The pictures show a QWERTY Xperia handset with black front and white back running WP7 (or maybe WP7.5). The tipster said that the handset is running beta Windows Phone software and works without any bugs. As we said previously, we believe that this is an old prototype and would be very surprised to see Sony adopt Windows Phone, at least in 2012. See the pictures below.
