OK, I tried to download the ROM for 7290g from

1010.hkcsl.com/jsp/biz_1010solution/biz_1010solution_1010office_bb_e_help_support_down loads.jsp]{CSL1010}

After extract the downloaded file, goto

C:\Program Files\Common Files\Research In Motion\AppLoader\<ROM Folder>\java

Dig out the file net_rim_font_chinese_hong_kong.cod and create a file net_rim_font_chinese_hong_kong.alx.

You can also come to this site to download the files.

Use the Application Loader to load in net_rim_font_chinese_hong_kong.alx and here you will have the traditional chinese font in the BlackBerry 8100
