DJM-450 and iPhone 7

Hi,

I have two questions:

1) I would like to know if someone already tested the DJM-450 with the new iPhone 7 (as in the website there is no mention for the seven).

2) Which kind of applications are compatible with the DJM-450 USB out? Only the RMX-1000? Or it is also possible to use other Apps, Android Devices, Another laptop, etc.
