When there's no data to transfer, Bluetooth with a DUN connection
established (ie. GPRS) consumes slightly less than WLAN connected to
an AP. But I suspect that you can't see the difference in real life.

But when you are transfering data, bluetooth is significantly better.
WLAN is quite a power hog.

I don't know much about bluetooth. But I would assume that having the
bluetooth enabled but without established connections consumes very
little.
