Now and then you will see posts on Facebook where your friends just got their hands on a Blackberry and are excitedly updating their status with their BB PINs asking for their other friends only Blackberry devices to add them so they can BBM each other. Apparently such occurrences are popular in Asia and South America, but either way if you want to look for more BBM contacts without having to blast out your BB PIN to your entire Facebook then SearchBBM could be the tool that you are looking for.
What the site does is that it connects to your Facebook to search for BBM contacts for you to add. We can only assume that it will integrate itself into other popular social networking sites such as Twitter and LinkedIn. Check out their website for more information, alternatively you can check out their video here where it is explained a bit further along with some demonstration.
