MP3 to Chocolate through Bluetooth?

Ok I have been trying to figure out the best way to do this. I got the memory card but removing it everytime I want to add songs is a hassel. I'm wondering if I can put MP3s on my phone through Bluetooth (my laptop has bluetooth) or if I need to buy the stupid USB cable. I've looked at different sites and some say Bluetooth MP3 transfer is impossible and others say it can be done. If someone could clear this up for me that would be great.

I second that question, cheers.

Anyone know where to find an unlocked Chocolate?

I would be interested to know as well if there is a way to update the Chocolate, maybe with a new app, that would allow it to accept files pushed to it via Bluetooth.

I have transfered a video using bluetooth. Music may be possible

It would be a lot slower though. I would just buy the music kit. It is a lot of money, but bluetooth takes a long time.
