Sorry for bringing this back.

If we direct the user to fMMS, aren't we doing, how to put it, a little wrong thing in the long run?

Let me try to explain.
User puts fMMS and he's happy, and everything is ok, but in the end at Nokia support they look at the complaints and conclude: "Look we were right, no one needs MMS function, because no one complained that it's missing, so the next device doesn't need it too."
Don't know how corporate world works, so I'm maybe wrong in this, but I think customer support at a company gives invaluable information of what the customers need/want and what should the corporation improve.
Maybe we could tell the user: "Here's the solution and please write to Nokia support that you had this problem and that helpful people at maemo.org has helped, but you would like if this basic function was working without any additional work from a paying customer."

This way the user would be happy, because it works, but Nokia support would also get valuable feedback.
