not about the iphone, but similar interest...

i just got a P900 from a friend - it syncs to my macbook pro geniously easy and ical and adressbook exchange data without me even doing anything, but i can't seem to send mp3s and software to the thing.

it came with a lot of software for windows, so i switched over via bootcamp, but man forget windows if you want to sync a phone - no way unless you have studied for it.

so now i'm looking for a program or generally a possibility to install software on my P900 without the pain of getting a card reader or switching to impossible windows applications.
anyone got any news for me?
