This has been asked in the past on the forums but no one had a solution. Well some time has gone by since the last post about it. So is there any way to have Bluetooth running in airplane mode? Or is there a way to just shut off the cellular radio? I am not looking for this to use on an airplane, I just want to be able to use my phone to output music to my Bluetooth speaker when I am out of range from any cell towers. I don't want it to keep looking for a signal and killing the battery.
