Seems like people want Sony to make a Windows Phone even if they don't seem keen on the idea. Take these latest images being reported tonight at XDA Developers (main site) which purport to show a device that looks like an Xperia Arc S running Windows Phone 7.
Although we'll say "anything is possible" and clearly Sony was working on Windows Phone back in 2010 (e.g. "Julie" prototype), we're doubtful that this is legit. Reasons? Well obviously it is missing the three keys near the bottom: Back, Windows and Search which have been on every single Windows Phone since day one and are a hardware requirement. Sure, that "arc" near the bottom could double as those (they're buttons on Android) but we find it odd that Sony would get rid of such a defining feature, let alone modify it to such a degree by removing those icons.
Going further, we don't see evidence for a side camera button. Now in fairness, these aren't the best shots and perhaps the button is there and just really flush, but it's one more thing we see that makes us question the validity of these images.
So while we really want to see Sony enter the Windows Phone game, we're calling this one fake. Plus we'd hate to think that Sony would, pardon the pun, phone it in this badly with their first Windows Phone i.e. just recycle an Android device. But hey, we'll see what happens at Mobile World Congress in a few weeks.
