I try it on my Galaxy Gio (GT-S5660) with CM-7.2-20120326-NIGHTLY-GIO installed and it work,
but there is weakness, the letter in the tut is not so bright (you can see in picture) except that everything is work perfect.
Now i can show you how to install it :
1. Your HH must be rooted, install this root explorer
2. Download material :
3. Move touchwiz, libxt9core.so, libdhwr.so, Axt9ime.apk to your HH using cable data.
4. Extract and move T9DB.7z to you HH, folder must be same name. T9DB
5. Open root explorer, copy touchwiz.xml to /system/etc/permission
6. copy libxt9core.so and libdhwr.so to /system/lib
7. copy AXTT9IME to /system/app
8. copy T9DB folder to /system/
9. set permission for all file that you copy like picture below.
10. Reboot your device so Samsung keyboard can active.
11. On CM-7.2-20120326-NIGHTLY-GIO there is no setting for keyboard you wanna choose, so if you need to change you must go to messaging and press and hold setting on keyboard. it will pop up keyboard choice.
NOTE:
BEWARE WHEN YOU USING ROOT EXPLORER YOU CAN DELETE A SYSTEM FILE WITH IT, SO BE CAREFUL
