I've just read where Windows Phone doesn't use MMS by default, which I guess is more cool than SMS. I looked it up and see that its about multimedia messaging, but I guess I don't get it. I've read where group messaging with Windows Phone isn't enabled. I don't get that at all. I've got a group on my WP, and easily send SMS messages to everyone on it. I've just tested taking a photo and sending that to everyone in that group. Works fine. What am I missing?
