I'm not 100% sure what's involved in jailbreaking iOS, but I'm pretty sure on a rooted Android you could put measures in place to "fake" results for any root checks the Facebook app would run. You could patch any APIs Facebook could use to make such checks.

Indeed, that's the whole point of having "root" --- to have complete control over the device and what the applications on it see.

It is a bit of a cat and mouse game, but as the long history of software cracking shows, as long as they still own the machine, the crackers always have the upper hand.
