Just spent 30min on the phone with AT&T. No dice with it. I have the camera icon and everything, IPCC file, but it wont let me send anything. AT&T said there is nothing to change on the feature. I saw that my bill had MMS Opt Out, but maybe there is supposed to be MMS Opt IN/OUT. I think AT&T doesnt want to change anything yet.
Seems likely. It's sad that at&t can't just make the switch happen now.
