Q: iPhone 3G, GPS, and Airplane Mode
I haven't found a post covering this, so I will give it a go here.
Why does the iPhone 3G shut down GPS when in Airplane Mode?
My work is easily disrupted by transmissions from devices like mobile phones, bluetooth, WiFi, etc. So I have always purchased phones with an airplane mode, so I can continue to use the PDA functions of the device, without having the extra radiation issues/interruptions.
Airplane mode is named for its original purpose, to shut down all radient functions of a mobile device while in flight on the somewhat dubious fear that amplified radients from a mobile device could disrupt aircraft electronics, supposedly causing anything navigation inconsistencies to crashing the airplane.
The thing is, GPS is a non-radiant function, it does not transmit data, it listens to and processes data from a navsat constellation overhead. Since it is a non-radient function, why is it disabled in Airplane Mode, which is function specifically design to suppress radient functions in mobile devices?
Are there any Apple people reading these forums who can offer a rational? Because to me, this makes no sense.
