Hello, nice to see this little issue have allready been solved. I am only posting because I share the interest of listening FM-broadcasts by mobile phone;
I have used my phone many years now at my work in a noisy factory, where I need to use ear protection. It's very convinient to plug in a phone to the ear protectors ( which have loudspeakers ) and then I can both listen for FM-radio and mp3-music - and I can use my phone at the same time with hands-free. So this is must for me, while I spend eight hours a day in this situation.

Perhaps bying N900 anyway - now!
