I got one more very basic Q. It might sound stupid, but just to make sure. Is it like you can update the Amplifi Frimware with iPhone from the "beginning". The idea is, that you shoulnd't need a MAC for that, but a bluetooth connection and an IOS-device should be enough? I can find my Amplifi with my iPhone and the bluetooth works okay, but I just can't upload the firmware, like I said before, and because of that, I can't control the amp with my phone.
And one more, it would have been nice to have the usb-cable with the amp, if it's that much needed.
