One problem left: cannot display Chinese characters in SMS (traditional nor simplified).

I have not touched my default english language Sprint OS (v.5.0.0.484). (I live in the US).
I followed the above instructions and installed all those CODs and the JADs..
I can now receive and send Chinese email, and I can SEND simplified Chinese SMS and ppl in China can read it.
However I cannot receive Chinese SMS!
If anyone sends me an SMS in traditional or simplified it comes up garbled as those characters like ÿăÝÈ¥å.

Any ideas?
I would download a Chinese OS for Tour 9630 but I haven’t found any.
