Here is what worked for me:
1) Download this file: (CLICK!) Then unzip it, and place the .ipcc file on your desktop.
2) Assuming you are using a Mac, running the latest iTunes (8.2) and have already installed iPhone 3.0 software... Quit iTunes, then open Terminal.app (~/Applications/Utilities/) and copy/paste the below command into the Terminal window:
defaults write com.apple.iTunes carrier-testing -bool TRUE
then press RETURN.
Quit the terminal.
3) Open iTunes.
4) Connect the iPhone via USB.
5) Hold the Option key down while clicking the "Check for Update" button in iTunes (you know.. the one you've been clicking ALL morning long.. lol. This will bring up a Finder window navigate through.
6) Navigate in the Finder window to the "ATT_US.ipcc" file on your desktop, highlight the file, then click "Open". iTunes will inject the file into the iPhone very quickly.
7) On the iPhone.. go to Settings>General>Network> You should now have a new tab/button title "Cellular Data Network". (If not.. reboot your iPhone to make it show up).
8) Enter these settings: MUST BE EXACT CaPs MaTtEr!
9) Reboot your iPhone.
10) On the iPhone go into the Messages app. You should now see the little Camera icon that allows you to take or choose a picture to send via MMS.
11)Send a test MMS to someone... it will fail.
12) Take the SIM card out of the iPhone and put it in another NON-iPhone (we'll call it 'Phone B") AT&T phone that CAN send MMS.
13) Try to send an MMS with phone B using the iPhone's SIM. It will fail. Now make 4 or 5 phone calls over about 20 or 25 minutes with phone B still using the iPhone SIM.. Try to send another MMS with phone B.. it should work!
14) Take the iPhone SIM out of phone B, put it back in the iPhone. Now try to send an MMS... it should work now!!! if not, reboot the iPhone and try again. Then you'll finally have... this:
