In the latest BlackBerry 10 Dev Alpha OS update, some sleuthing found a few hidden gems burried in the OS. When diving into the embeded icons, BBVietnam came across the icon set for the device that included not only Facebook, Twitter and LinkedIn, but also Skype. Yes, that Skype. Now we can't say for sure what this means (if anything) but it is a good sign. We've had no official word on either side as to if Skype will be available for BlackBerry 10 at all, but the icons do get us a bit curious regardless.
