Some help needed in this Ext_Rom

---

Hi all.
For 3 days now i have a S200.
Well, in my opinion, the same as 9100, but without the keyboard.
I want to install another rom, but before that, can someone tell me if any of the cabs in the Ext_Rom are the settings for my carrier?
I use TMN in portugal.
I've already seen the TMN_S200_WWE.CAB but i think they are only some .tsk and jpg.

If someone can help me out, i'll be glad.
Btw, what is the best method to backup the rom, os and GSM?
