Its a social app for Twitter, Facebook etc.....still in beta phase and you need to be invited by Socialscope themselves, the beta testers dont get invites to hand out.
It's probably the most sought after application for BlackBerry that I know of. All you can do is sign up for an invite at SocialScope - A Mobile Inbox for your Social Networks and wait like everyone else. I do prefer SocialScope over the Facebook for BB application...
