With the FM radio application installed there's suddenly an issue with the Internet radio application that didn't exist before:

I have the N800 rigged up with earbuds as antenna (nicely stretched out for best reception), listening to the radio on the speakers. I have the FM radio applet sitting right below the Internet applet, they look very similar, and I can easily switch between them.

The problem is that the Internet radio automatically uses the earbuds because they are plugged in as an antenna for the FM radio! So when I switch from an FM channel to an Internet channel the speaker sound disappears.. and I have to remove the antenna, and then I have to plug it back in when I change back to FM radio (and then that one tends to switch to earbuds instead of remembering the setting, but that's for another problem report).

In short: Now I need a configurable earbuds/speaker selection in the Internet radio application too..!
