Bluetooth MP3 transfer to 8830

I'm trying to transfer MP3s via Bluetooth to the media card on my 8830, and I hit a little snag. I researched the process and found an excellent tutorial [can't post links yet], but it covers the Curve models...

The problem is that I can't seem to change the destination on the media card. It wants to dump any MP3 into my ringtones folder. I can see the field where I should be able to change the directory, but it won't let me click into it or change it. I want them to go to a music folder that I have created on the media card.

Suggestions?

Thanks,
Josh
