Actually, I have a phone running Android 4.0 here, so I tried pairing it 
with the laptop from the phone side, but there was no bluetooth card 
showing up at all on the laptop side, and all in the gnome bluetooth GUI 
is a checkbox asking me for network connections.

Maybe Android 4.0 (or my version of bluez?) does not support relaying 
audio to (or from?) the phone?
