Remove SIM-lock patch generator

Where can I find the main firmware for the w810i?
Do I have to download it somewhere or should it be on the phone already?
How can I recognise the firmware file?

start here : XS++ 3.1 Guide-Flashing, Customizing, Recovering - Top Sony Forums
for firmware, you will get it at download area

Oh right thanks.
I went here Top Sony Forums
There are so many different firmwares I've not got a clue which to use.
I'm from Europe and I speak English anyway and erm my knowledge ends there.

So am I right in understanding that you have to download some firmware put it onto your phone flash it using the XS++ 3.1 before you can actually unlock the phone?

ps. I checked the phone and it said in the software info section
R4EA031
prgCXC1250316_GENERIC_HN R4EA031

ok I downloaded these 2 files
W810_R4AEA031_FS_EUROPE_2_RED49.fbn
and
W810_R4AEA031_MAIN_GENERIC_HN_RED49.mbn

Are these 2 files ok?
Would they work?
I read somewhere I need the fs file aswell as a main file so would these files be ok for generating an unlock patch?

Do I need to flash the fs aswell as the firmware or just the firmware alone before I go about unlocking my phone?
