Your posts seemed inflammatory without any links or information cited, and the only information I have been able to gather from searches online are mostly links to sensationalist articles attempting to cause mass alarm.
The truth is there is no way anybody knows how to block the Dropout Jeep program from accessing your phone except to turn it off or use Airplane Mode (and even with the latter, there's no way to know if anything is turning on data momentarily to send out anything).
Nothing has been confirmed or denied by Apple or the NSA, so we still do not know if what is being said is true. My personal mantra is that nothing you do online is safe, and any electronic devices you use have the potential to be hacked.
While such a program may exist, I doubt that the NSA will be pushing or pulling any data on most average users, and now that it's out in the light (if it's indeed true), it will be harder still for them to do anything without fear of discovery or reproach.
