Oh man, I know what you mean about having to type in the phone number. I was just shaking my fist at the screen about that yesterday! So annoying. Usability fail.
In my experience, it doesn't seem to matter 'exactly' what type of document. It can be different than what they ask for on their website... it probably just needs to be something somewhat official that can't be easily 'faked'.
I have uploaded scanned documents and such before and it worked. I think you can even send a JPG or GIF version... so I would assume that if a scan works, a photo should, too.
I think that if the photo is clear enough... and you crop out the table, there shouldn't be a difference.
