MMS is outdated tech that needs to go honestly. Save fore a picture being send here and there, it's useless. Personally, I have sent maybe one or two picture messages. Neither of which panned out because they are of horrible quality when they show up on the other end.
That's why I never understood the fuss about iPhone not having MMS to begin with. Why bother. You have email, Flickr, MobileMe, Dropbox and numerous other alternatives that allow you to have FULL resolution and quality.
