I don't know about the phone meta data, but I do know that you tell the MSC what types of phones and mobile devices you use, and what company you use for mobile service.
As I've said before, I don't like doing cell phone shops, but I do a few here and there so that I can see what new phones are available. I was watching the cell phone shops a week or so ago, and there were some promising bonuses, but they were all for Apple owners or for AT&T stores.
Once upon a time they said if you do the AT&T audits you can't do mystery shops at AT&T stores, so I don't, even though it's been a couple years since the last time I did an audit. I will NEVER do a shop for an Apple product of any type, I won't own one and I won't use any service that Apple provides.
