Unfortunately the resolution is too low. I can make out some of the words on the bottom half of the document but that's it. If we can get @Reader to send when safe, that would be ideal.
EDIT: And I know this may not be entirely cool since @Reader is helping us, but the image of her phone also shows a string of photos along the bottom. Perhaps clues that the Devoted have been following? If they're ahead of us, maybe those thumbnails can point us in the right direction.
