From memory the basic procedure is
a) Download the OS you want to put on your device and install it
b) Start App Loader (part of Desktop Manager) and reboot your Blackberry and plug in it in
c) Hope that App Loader detects the device and then it will offer to install the OS.
There are some good guides out there to this sort of process, I woud search Google for something.

You download and install the OS on your PC, the DTM can use the installed OS's it finds to update attached devices.
DTM is actually smart enough to actually download and install an OS directly, but I never got that to work for anything but the most current OS available, so I don't think you can use that approach to downgrade an OS. but that is just my feeling, I'm not 100% sure of that.
Like I said before, there are good guides out there if you search for them. You might even find that the Curve forum provides you with more assistance than here too.
