Yep - he's pretty much nailed it on the money. I do believe, you can call AT&T and put a "data block" feature on the phone (free), so that it physically won't connect to EDGE if she attempts to. I'm not sure how they will feel about this with the iPhone, but I've done it before on my Treo 680 in the past, no problems.
Hope this helps,
