Yes, that's the one.
I couldn't understand why the baseband was using power in aeroplane mode either, but I am definitely using aeroplane mode when I am not using the tablet for any length of time. I keep it at the side of my bed at night and unless I use aeroplane mode or remember to turn the sound down it wakes me up when sync notifications occur.
For some reason the reception for my cellphone network is variable near my home, even though I can see the cell towers from my bedroom window.
