Funny, I had sent an almost identical message to Nokia Customer Service about 2 weeks ago. I got the automatic reply that they would answer me in 2 working days. And that was it. Never got any message since.... I spent only 10 Euros on music as I just wanted to check it out, but nevertheless it is a shame that they didn't highlight the incompatibility of the N900 on their site...

I would be very interested to hear about your experiences!
