Steve Ballmer made a surprise appearance at the BlackBerry World keynote. While Windows Phone is an obvious competitor to the BlackBerry platform, the Microsoft and RIM are establishing a partnership where Bing will be integrated into the BlackBerry devices. We aren’t talking about just a simple app where you can search, this will be integrated into the OS, allowing for voice and location services. This is likely to be seen in BlackBerry 7, but no launch date yet. Hit the jump for a video demo!
