Most of us have seen the ad for it. Is it real or is it a hoax? We will find out within the next 24 hours.
The thing is, it is NOT an ad; nor was it ever said to be an ad. It was allegedly an internal communication to employees. Even if it were real, there's no false advertising when the document wasn't even meant for public viewing. It's one of those memos that is a "heads-up" to employees, so they know what is going on when a bunch of people suddenly start coming in with a totally different OS on their device.
This may be the day the soak test will begin pushing, as that could affect devices sold by Best Buy.
