How are you running Proswitcher on 3.2.1?
Jailbreakme was broken on 3.2.1 until (possibly) a short time ago (or still is).
Oh, so maybe it is fixed (edit - looked at timestamp)
Did you install the newer (alpha) version of Proswitcher? - Not sure if the repo is included in latest JB - in 3.2 we had to add it manually.
