I thank you all for your kind replies. I "almost" have all my questions answered.

It seems MMS will be 3rd party. atleast for now. I'm fine with that.

However, no word on Portrait Mode.

I understand the possibility of a global portrait mode is not strong for Maemo 5. it seems to be a Maemo 6 planned feature.

And we cannot claim we didn't see this coming. The N900 Logo IS PRINTED on the phone in Landscape after all.

HOWEVER, and again I plead with the devs. how about a compromise?

We just need the following things to be Portrait. That's all. at-least for me.
1. Menu for launching stuff (and if possible the file manager)
2. SMS/Conversations
3. Email
4. On-Screen Portrait Keyboard (uKeyboard mod? I can help just tell me what to do)
5. Browser
6. Media Player (If video is too tough, then just music will do. Yes I know there is Pennuci for audio, but the built in player is better)

Just give me those 6. And I'll be happy along with many others.

The Desktop, icons, widgets can remain Landscape. I don't mind.

Using the Braek glitch, many of those work just fine in Portrait. so we're like almost there.
