As part of revamping BlackBerry Messenger, BlackBerry is bringing support for video chat and voice calling to the popular app. Voice chat was expected after beta versions of BBM 7 included support for Wi-Fi calling. With video conferencing, clearly the company has its sights on existing apps lke Apple's FaceTime and Skype. Additionally, there's a new feature dubbed Screenshare that will let the person you're calling view everything on your BlackBerry's screen. Thorsten Heins claims it makes for an easier and faster way to share information without needing to leave a call to write an email or send an SMS message.
