In my experience, when I log the Maemo chat plugin in to Facebook, all my FB contacts show in the Maemo address book / contacts app.
some of them I have contact with in real life or by phone, others only on FB.
These FB-only contacts I don't want showing in my phone address book. However, if I delete them, there is a message saying that they'll also be removed from FB.
How can I remove them from my phone but keep them on FB?
Thanks, Ben
