After some headaches trying to get it up and running, I created two step-by-step instructables guide to setting up a bluetooth python console on your mac from your phone.
The first guide sets up a basic python console which you can connect from your mac without installing any additional software.
PyS60: Python console from your Nokia phone on your Mac
The second extends this setup to use PUTools for a more advanced console (syntax highlight, command history, file sync, etc).

Just thought people might find these useful if you're developing for PyS60 on the Mac.
