AFAIK it isn't possible. It has to reboot the phone and erase it to the proper install.
The music you are worried about losing is on your iPod? Or are you worried about the iPod overwriting your iTunes library? It should copy your music from the phone when you sync, but that could be a feature introduced in a later revision, or perhaps only for content you purchased on the phone.
I have a mac utility for moving stuff of an iPhone/touch, but this looks like a possible way to pull files off:
There are some commercial tools (many of which are constantly spamming here), but I can't speak to them.
