Current bugbears

[Claes Mogren]

I call bullshit on this signal restriction. How come they've successfully
had wifi on planes without any problems? And I know that people have their
phones on all the time while flying and I've never heard that it has caused
a crash or even been noticed in any way. Can't imagine that there's any GSM
signal to pick up a 30000ft anyway when you move at 800km/h.

Also, if GPS is bad for the planes, how come the US is going to use it to
navigate the planes?

)

Anyway, back to OpenMoko. I agree that it's good to have the option to turn
all wireless communication off on boot, with a timeout of 10 seconds or so.
Default should be the same settings as you had when you turned off though.
