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.
<br><br>Also, if GPS is bad for the planes, how come the US is going to use it to navigate the planes?<br>(<a href="http://www.theregister.co.uk/2007/09/04/gps_satnav_air_traffic_for_america/">http://www.theregister.co.uk/2007/09/04/gps_satnav_air_traffic_for_america/
</a>)<br><br>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.
