Has iOS 8.3 changed airplane mode into keeping the GPS receiver active in airplane mode? I put my iPhone & iPad into airplane mode, and turned off both the wifi and Bluetooth. I then went into my navigon GPS app (which uses an internal map database) and it appears to be able to navigate, without GPS warnings and showing 16' or 32' accuracy on the status page (Wifi only positioning is way less accurate than 16' I believe, and with the wifi off it should not be able to use wifi trangulation anyway.) Is this an undocumented change? Could anyone else running 8.3 confirm they can use the GPS in airplane mode as well?
