I did a similar thing, but enable Far East language display on TM506, which only has T-Mobile US version
if you have another SE phone with Far East fw (APAC, Hong Kong, China, Taiwan), you also use this method to extract fonts as well as other files (total 5 files)
enable Chinese/Japanese display on your TM506 (or non-Asian region SE phones)
I put a tutorial over there, as well as here (search TM506 thread)
