I've never once wanted to use MMS. On this phone or any other. I do now send pictures to people since the iphone actually has a usable camera (compared any other picture phone I've owned), but I e-mail them since I don't know if the other person has MMS either.
I don't think the API restricts GPS turn-by-turn; in fact, last I heard, Garmin was going to write a turn-by-turn GPS app for the iPhone.
Opening up the phone completely just isn't possible for Apple. I know it would work well for you personally, but it wouldn't work well for most people. It's paternalism, but it's needed for most users.
Chill out, let Jobs get better. He seems to know what he's doing, despite your certainty that you could do his job better.
