Installing languages on w910i

Yo everyone!

Recently i bought sony w910i phone, and was playing ard wif it. I wanted to add more languages to it such as Japanese so I was wondering which file to download and to go about installing it.;)

I went to the download page and saw EMEA_1 - wat does tt stand for?

Thanks?

Look w910 is a new platform phone ( db 3150 ). Xs++ 3.1 does support detecting your phone, but nothing else ( flashing, changing languages ... ).
For now you can`t change anything.

Nice day
