I've been looking at the Airplane Radios action which should allow you to selectively put different wireless technologies into their own individual Airplane modes, rather than put the entire phone into it. I was thinking that at night (during my Tasker-controlled quiet time) I'd put cell service into airplane mode but leave Bluetooth and WiFi on. It doesn't seem to do anything though. The icon top-right (and in the Internet settings screen) it looks like I'm still connected to my phone provider.
