I have been reading around about tethering and mms. It seems that a lot of people that have mms already have at&t 5.0 were many other people have at&t 4.0, to see what you have look under settings->general->about and then carrier to see what you have.
I have updated to at&t 5.0 and have not seen any change, anyone know anything about this.
These are the steps i used to upgrade from 4 to 5.
I only used the first step, i downloaded the file for the carrier settings.
