possible to go back to German rom?

[john]

hello,
I finally upgraded my German MDAIII to the WWE rom from I-mate.
Unfortunately i see that the keys on my keyboard just don't match. So i'd like to flash it back with the german rom.
Is this possible?
Do i need to use the devicedata for my batch file from i-mate now? or still the original T-MOB101 and GER?
where can i download the geman rom?
thank you for your help.

asking me to upgrade radio from 1.02.00 to 1.06.00 etc....
should i proceed?
has anyone done it already?
