I can't find BBM, though it shows up -- twice -- in the Options > Device > Applications Management screen (v5.0.1.34, which is undeletable, and v5.0.1.38, which I can delete), I was a Beta Zone tester for FB 1.8 but my keycode isn't accepted after the 1.8 beta was Device Switched onto the Torch (overwriting a non-beta version of 1.8), and there are two versions of Twitter, but that seems to work OK.
In short, if you have any BB "Add-On Apps" on your old phone -- get rid of them before you run Device Switch.
