Dude... you were the one that asked "How so?" in response to a statement that nothing of value would be recovered from the iPhone that the FBI was using as a means of creating a precedent. I gave you the "how so" reasons, I didn't say anything about not exploring reasonable sources of information. If FBI investigative time is a scarce resource, I would expect them to prioritize the sources of information, putting "less likely to yeild results" lower in the prioritized list. I would also expect them to stop investigating the material way down on the priority list if the material high on the priority list had yielded results.

Dude. Clearly you have insights into this investigation that neither I, any media outlet or even in fact the FBI even has. So in that case, congrats, you win.
