mmm... well it's kinda like the position i'm in. my phone was purchased in NY, and i got what i believe to be a spanish keyboard. i have installed traditional chinese/english on the phone. when i input chinese - i don't have a problem because the strokes input only requires me to use 5 keys (QWEAS). when i input eng, however, the symbols (blue ones) remap, even though i've tried to keep my firmware as 0529664 Euro-E1 Silver (default).
however, this is LITTLE problem for me, to be honest. when i do need to use symbol, i just click that key at bottom righthand corner ("Car" or "Chr"), and it'd work just fine. one extra step, but too trivial to complain, really.
so either way, only your symbols change. does this answer your question?
