I'm using Quicklaunch and I have facebook in my list of apps. I also added the mobile website into my QL through the website button rather than the applications. So I have two facebook choices when I open my QL.
Afraid I don't know why it isn't in your list of apps.
Are you using stock OS or any hybrid? The only thing I could think is the hybrid I have that already has facebook installed (I mean installs it when it installs the OS) did it.
