You'll need to update your carrier settings by plugging in your iPhone to allow iTunes to see it, then go to "Check for Update." The update adds a 37k file (at least on the Mac), named: 'ATT_US.ipcc' file to your /Users/[Username]/Library/iTunes/iPhone Carrier Support/ folder if on a Mac.
In Windows XP the file is downloaded to: C:\Documents and Settings\[Username]\Application Data\Apple Computer\iTunes\iPhone Carrier Support
In Vista the file can be found in: C:\Documents and Settings\[username]\AppData\Roaming\Apple Computer\iTunes\iPhone Carrier Support\
The install just takes a second and you then need to restart your iPhone. When you do, your Messages app will gain a small camera icon to the left of the input box. Tapping it will bring up a screen allowing you to take a picture or video or to use an existing one from your iPhoto library.
Sending is pretty slow. This could be due to everyone trying it at the same time. One picture took about 20 seconds on Wi-Fi and a 5 second video took about 30 seconds to transmit.
The quality of the received picture or video is just as good as you hoped it would be. You can read more about iPhone carrier settings updates on this Apple support article.
Thanks to everyone for sending this in!
