Treo 750 Clear MMS Settings

[lcavada]

Yesterday just got an "unlocked" Treo 750v (Vodafone Version).

The MMS settings are buried in the registry. Cannot get to them via typical set up options.

There is no way I can replace Cingular MMS settings with Tmobile (My carrier).

If I go and make change manually, the changes do not take effect. The next time I reboot/restart phone these settings disappear.

I have found registry import files in different forums, but none seem to make change properly.

Any ideas?
