Interesting point I'd not considered from Christopher Kobayashi, on the Keitai-L list: "Kind of spooky to think that there's web connections in the background
without the user pressing a link/button. Basically meaning that
they'll be charged without them knowing it.
If you're on a unlimited data plan this wouldn't matter much, but what
about the poor souls not on this plan. Bad people can make things
expensive, or is there a limit to this..."
