I had a problem with 6.0 because I was using the Mac-ID of the wi-fi device to construct a unique ID for each specific device (It is the way my side-loaded app does licensing). Starting with 6.0, the MAC-ID is no longer available. The OS returns a constant with lots of zeroes. I had to scramble to come up with an alternate source for a unique device ID.
