Help! Wizard EXT. ROM question?

[alexel]

Hi, I am newbie in hacking into preinstalled content of my wizard. I have installed T-Mobile Rom that has some kind of protection which does not let me to change MMS settings (it has installed settings that I can not edit nor can I delete it). I've tried downloading network configuration wizard but there is no configuration for my country... Everything other regarding this rom works fantastic and smooth...
So I menaged to make EXTENDED ROM visible, and downloaded new Arcsoft MMS composer (hoping that this will make a difference) but now I can not find cab file in ext.rom that represent mms composer, which I would like to replace with new mms composer.
Can you help me, and tell me what to delete from my extended rom? Should I delete mms composer from ext.rom or some other cab with t-mobile settings.
Here is my config.txt from extended rom:

Can you tell me what to delete or replace? What is unnecessary from above?
Thank You very much in advance...

If you are using a G4 (or locked G3), you have no way to remove any files in ExtROM.

Thank You... I've just realized that:( I guess I will have to use it without mms or gprs... Anyway, it's a great phone...

Thanks anyway

Can't you do a HARD reset, then after the phone boots, Soft reset before the extended rom loads, then manually setup your MMS/GPRS?
