Couldn't an American request a FOIA for this to see what's the level of information gathering on iPhone users? Could EFF sue them for it or something to unveil more?
I have no idea. There are a lot of assumptions implicit in that question.
I'm just saying that you are unlikely to be successful in requesting more information for this file. Information that "could reasonably interfere" with law enforcement is exempt. Also, the FBI does not make it easy to request documents form them and, further, the turnaround on a request can be months or years.
