I hadn't thought about it, but yes it is odd. Since MMS counts towards a message count and (if no message plan) data. There really is no reason to be able to turn it off or on, since we are required to have a data plan and we cannot turn sms on and off.
This may be because ATT hasn't set up the MMS for iPhones yet. Possibly, when 3.0 official comes out and ATT is ready for MMS on iPhone, it will only work on 3G service. ??????
