Where would I find this MMS opt out on my bill? I have gone back in my full bill history a full year and cannot find any MMS opt out on any bill. Additionally, all of these bills list my texting plan as "MEDIA MAX 200 MSGS". Under billing detail, the Feature code for all text messages up to and including 06/18/09 is listed as "Integrated Messaging". After this is when I upgraded to iPhone 3GS. There is no listing in the Feature Code column. Additionally, on this date the messaging rate code changed from "AMS1" to "MSG5". I don't know if this means anything. It could just be the change from original iPhone to iPhone 3GS, but here's hoping that it's a sign of MMS on the way?
