Is Sony making a Windows Phone? The rumor started to get serious way back in December 2013, although, since then, nothing substantive has come about, suggesting either the info was bogus or talks fell through. Indeed, Sony has spun off their PC business recently, suggesting a cooling with Microsoft in general, (and forfeiting any future tie-in).
Now, Sony has an app for Windows Phone but before you get too excited, it appears to be nefarious tool to get you to switch from Windows Phone to Xperia with Android. The app is dubbed Xperia™ Transfer Mobile and it is part of Sony's program to ease those coming from iOS, BlackBerry, and now Windows Phone onto a new Xperia with Android.
