Try to do the following please:
Install rootsh from Application Manager, open terminal and type:
sudo gainroot
mv .modest modestbackup
Then open modest (email client) and try again.

Attempted, still not showing. When I did flash the device I flashed firmware
then, cleared emmc following...could that have anything to do with it? Was
thinking about trying clearing the emmc then flashing again...

You could try that, as it's what the wiki says, when reflashing don't add -R at
the end, after reflashing both, type flasher-3.5 -R

Reflashed accordingly...still no luck

For future reference, please do not set priority to High.

Can you try flash eMMC and firmware as well to bring the phone back to factory
state.

Well sorry about that, it's just a high priority issue to me as well a few
others i know having the problem. It's very frustrating becuase I cannot find
an answer as to why this happens or means to fix my issue. I've done the
reflash and so have others, tried diff. sim, selected different regions, and
removed the battery; everything...

Priority is set by developers. 

Have you flashed eMMC?

Yes quite a few times as stated...

Just reflashed, and I can confirm that Nokia Messaging is visible.
Closing as WORKSFORME

What are your country and region settings, which country and provider is your
SIM card from, and which eMMC image do you have (if you know, like in which
country did you buy the N900)?

Are you letting the device check for Nokia services?
If so, it's not available in your country.

US on tmobile, was there before but did reflash with latest bin and also emc
and no longer there...i ordered att sim off of ebay to try since that
apparently is the only fix...

Please also answer the rest of my questions...
(And please do not fullquote and do not answer above the quote.)

I seriously dont get what your not understanding....Its a us sim card and it
checks for service providers i select us and no nokia messaging is there and
sorry for not knowing the entire name of the bin, i use the vanilla emc and the
latest available bin file. All of which i've answered, this bug report has been
goin on forever. The only fix seems to be a cingular sim card with the n900 on
wifi

confirming that att sim method works on wifi

(In reply to comment #17)

So the issue for Nokia Messaging not showing up is being you're connecting to
carrier's network when attempting to retrieve the providers? And that the
workaround/solution for this is to connect via Wifi and retrieve the providers
instead?

Can you confirm?
Thanks

Yea believe the issue is related to tmobile's issues with data packet
connections. Have a friend that like me just lost his nokia msging today and
many others on forums around with the issue on tmobile. I ordered att sim off
of ebay for 5 bucks plugged it in (non activated) and used wifi and it pulled
in the nokia msging carrier keyed in my settings, turned the phone off and
placed my tmobile sim back in now i'm good to go

I also see this with my US T-Mobile SIM Card in.

Did the dev that marked as WORKSFORME actually try with a US T-Mobile SIM card
put in ?

There was no dev but the reporter.
Feel free to file a separate new report with exact steps... Thanks!

Andre,

I got confused because the only mention of marking as WORKSFORME on the
comments is from Mohammad.

I now looked closer at the bug activity and saw that submitter also marked it
as WORKSFORME later:
However I don't think that the submitter using an AT&T SIM tp sidestep the
issue constitutes a valid reason for a resolution with WORKSFORME.

The issue persists with the exact same steps as originally reported.
Just so I understand, you wish me to file a new bug, so that it gets marked as
duplicate of this one because it has the same steps ?

Comment 23 Andre Klapper 2010-06-23 16:29:16 UTC

Yes, a clean and new report, specifically for your provider (please mention in
the summary), with exact steps. Thanks. :)
