Apparently one can do it from a jailbroken iPhone, but her iPhone is not jailbroken. I looked this up the last round we went with Joe. *twitches*

Maybe I can accidentally knock her iPhone off a balcony and convince her to, like, leave The Man That Is Apple and get a phone that will allow her to do things.

...I wonder if that would work, actually. Or if I could convince her to just switch phones! ...wait, she's probably on A Plan. (Huh, I wonder I can block numbers on my phone? Just out of idle curiosity.)
