How to add t9 language to T707

I buy a T707 for my girlfriend but it does'nt have Spanish dictionary.
I have being reading lots of threads and now I am trying this method

but i still have some questions:
1.-I think i need SEFP that supports CID53 to be able to connect to my phone, the question is where can I download that version of SEFP for FAR manager?
2.-Does any one know what is the CID number for the T707?
3.-Can I use a t9 file from any sony ericsson? I have downloaded one from a K750

If you know the answer for one or all the question please hepl me, thanks in advance.
