Download the facebook app for the onyx. I was like huh? Does this mean a new BlackBerry soon? At first it said Storm (which seems ok since the Tour is based a little on the Storm 1). I wish I knew how to upload a picture but if you have a Tour go to the facebook mobile site and login and look at the very bottom of the page..
