Try and actually understand what people are telling you.

This is definitely not a preschool, but your language tends to make one wonder if you may be a student thereof. It would be much better if you could actually articulate your desire in a less combative manner.

So you want MMS to be integrated in to conversations - well, short and simple - it cannot be done, and it never will be unless Nokia make it so. Conversations is closed. That is not the fault of anyone here, asking for something better will not get you very far, the best is fMMS, if it doesn't do what you want then you've reached a dead end.

You have one option. Write an application that replaces conversations (every feature thereof) and includes MMS. To say this is non-trivial would probably be an understatement.
