Have the ability to detect running in emulator or simulator vs real device

Google search on how to do this gave me nothing useful except http://stackoverflow.com/questions/20761520/phonegap-detect-emulation . But when I try to do what the answer suggested device.platform gives me iOS device.model gives me x86_64 . There is basically no way for me to detect whether I'm running inside emulator or real device. Is this a regression or something?
