We knew when RIM released the BBM SDK that there would be many apps jumping on the bandwagon to help you meet new BBM friends. The latest comes from S4BB and promises to help you “reach out and meet new people” through BBM. You setup characteristics about yourself including age, country, gender, interests, language, location, and time zone and the app will match you up with new friends.
Pinbook seems to be free during the beta period but the description says it has a “30 day value back guarantee” which hints that it might not remain free. Check out the Pinbook beta for yourself in App World.
