I found out how to get MMS working if you are getting the red exclamation point. Apparently when ATT removed the opt out code on iPhone accounts they skipped some accounts for one reason or another. Here is how to get it working again without calling or chatting with ATT. Go here and register: https://www.wireless.att.com/sson/registration Once you register completely MMS will magically work. Remember this only works if you are getting the red exclamation point when trying to send an MMS. Good Luck.
