Whenever anyone on this forum dates to suggest they would like MMS they are guaranteed to get multiple replies from people saying "I don't need MMS/I never get MMS/emailing a photo is better than MMS/you can email a photo to their mobile number. I agree with the OP, I want MMS for crimbo too!
The decision to leave out MMS is just bizarre, and people finding the need to defend the lack of it is even more bizarre! My iPhone is the best phone I've ever had, I love it, would not go back to any other phone, but I am not about to say it lacks certain features. No-one else I know has an iphone so I get sent a few. MMSs and have to go to o2s site to read them , I'm pretty fed up with this after only a month. Would be very happy of apple released a MMS upgrade for Christmas, but I think we'll have to wait for the SDK.
Another feature I'd like is the ability to save a picture from an email (or MMS) to the photos app.
