Remember back when Apple said iPhone OS 3.0 would enable MMS functionality at their Sneak Peak event, then again Apple said MMS would be available by June 19th to everyone except AT&T.
But still no MMS for the iPhone with AT&T reports the iPhone blog. AT&T was incapable of supporting the incredible volume of iPhones they have exclusivity over or are incompetent in handling the roll out in a timely fashion.
But consider this, even if AT&T did offer MMS on the iPhone right now, would you use it? How many would use MMS and how often, and what volumes of MMS would AT&T really have to handle?
