how do i put french language onto a sony ericsson w995 phone???????

Hi everyone;
please; please; pleassssse can someone tell me how you put english; french & arabic on a sony ericsson w995 phone???
I have been on the internet for 5 days now trying to understand all of this stuff, I have no idea if the phone is black,blue, green; yellow or what the colours mean; or even which file i have to download to make it work!!
can anyone explain it all to a "Techno Unfriendly Being" !!!! (ie for a dummy!!!!)

many thanks to you all;:a018:

The simplest way I think is to flash S-ASIA-LEVAN FS (contains all the languages you require) & custom to it.
