Here is what his research confirmed:
There is a security check on newer Moto phones, if you ever root your phone they know.
To check root status check recovery. qe 0/0 = virgin qe 0/1 = rooted in past qe 1/1 = rooted right now. You can't reset the counter.
The recovery counter doesn't send info anywhere, but if you send phone back/in it can be checked quickly and easily

Disconcerting, to say the least.
I know for a fact that this is also on our BIONICs.
