We don’t have much information on this (yet) but it looks like an ASUS device running on Windows Phone 7 has been spotted in Pakistan. Unlike the LG Panther and Samsung Taylor devices that are only intended to be development devices for Windows Phone 7, this ASUS device looks like it could be a production prototype device that is being field tested. The image is small so it’s tough to make out details, but it appears to have a front-facing camera, or perhaps that’s a light sensor. Beyond that, we can see the button panel nicely adorned with brushed metal. More info as we get it!
