*UPDATE* Social feeds is available, you just have to check it in apploader to ensure installation.
Here is a super quick look at OS 188.8.131.52 running on a Verizon BlackBerry Bold 9650. I just pulled it off of my PC and haven't even played around with it yet. My initial thoughts are that it runs pretty well overall, but its a bit sluggish at times. It has all of the revamped OS 6 goodies in there like the new UI, WebKit browser and Universal Search, but sadly no sign of Social Feeds (unless I'm missing it). So check out the video and if you decide you want to give it a go head over to the original post.
