Ok, so I'm running the Ampd 2742 seem, on Vivo.
Email messages work. So far everyting is working. Trying to test another phone network. We'll see.

<EDIT>

Ok, so it looks like it works!. I got a pix message from my sister. And up until now, I've never been able to get any messages from her. She's got sprint, running on some samsung phone.
It's a bit of a cop-out I know. I have not learned what offset/bits are responsible for this. But if it is infact working as it seems to be we can atleast start to look into what it is. Or maybe just edit the seem for Vivo, and post it .

I have seem edits to do to enable mms server setup, and probably a good number of other things. But if this does infact work it's alteast some progress.

If anyone has a messaging plan on another service Alltel, Tmobil AT&T. I'd like to try and see if this is really working.

One thing to note. In the past when I got a message with no subject line, it would just say NONE for the subject. Now the subject says New Pix message.

Here is the Seem. Load it at your own risk. It's late, but the offsets seem off in this seem.
