Just like the full-blown AOL IM system, you can add buddies that are the phone numbers of cell phones you want to send SMS to, and you establish a two-way conduit. The recipient still pays for SMS (if they have a fee) on their end, but if it's another iPhone user, you could coordinate with them via SMS to use instant messaging instead."
If it happens once, it's a bug. If it happens twice, it's a feature.
If it happens more than twice, it's a design philosophy.
