AP 4.0 building language packs

[saeros]

Hello,

I have an HTC original ROM (OS 6) installed in my HTC X7500 which is localized to Finland. Besides the language of the OS and SIP keyboard the actual hardware keyboard also contains ÖÄ-characters.

Is there way to use my existing ROM to build a language pack for the AP 4.0 which would install the Finnish SIP layout, hardware keyboard layout and the Finnish dictionary. OS language does not matter for me. I actually would prefer to go English on that as some of the translation in the original ROM are pretty bad or too long for the buttons.

Updates:
Ok after some digging I found two files from the HTC Vox forums:

eT9 files for windows mobile 5, 6 and 6.1:

Keyboard layouts

Lots more can be found from:

NOTE: I HAVEN'T TESTED THESE YET AS I STILL HAVE MY ORIGINAL HTC ROM INSTALLED.

If anyone can five me some input as are these the customizations I'm looking for ?
