Alright, BlackBerry fans, this is truly something to get excited about. Building upon the excitement generated this weekend by a slew of new images of the upcoming 9800 slider, a video walkthrough of the device today cropped up on YouTube. The video does a pretty good job showing off the device and some of the features of the BlackBerry 6 OS and is only 3 minutes and 39 seconds in length, so the way we see it, you really have no reason for passing this by. We mean, RIM is pretty much guaranteed to have the video pulled in quick order. Oh, and notice the AT&T splash screen? We told you.
