I found that actually this feature is always in the phone. Just the latest firmware which is R1HA035 APAC version had disabled it but it has added few more application such as facebook, photo mate and etc. It is disable by default in APAC firmware. For ur information, my phone does not has it as i said in earlier time and i keep asking about how to enable it in this thread. haha

However, i dont think i was "flashed" it. Flash is something like "format" it right? i dont really know what's the meaning of flash. LOL
It just adding another customize file to enable/activate the feature as what you shown me in previous post.
I'm using a2uploader version 3.

It's quite easy actually. Just connect ur phone to the a2uploader and drag a file into tpa/present/custom.
Just an addon i think, because it does not affect all ur files. It will not be deleted after i did it with a2uploader. All contacts and files are still there.
But just backup just in case la bro.

This is the customize file that i had add in my phone. It contains normal sms mode which is the one you are using now  and threaded sms.
If you want  to enable the threaded sms, just upload the customize file in threaded sms folder  into ur phone. To disable it, use the normal sms file.

This is the first time im doing this thingy. 
Good luck bro

First time already successful?!!     

Haha, I was worried on the part where all the memory been wiped out, but in your case it seems it didn't. 
Btw, you are already considered flashing the phone since you access the tpa files.

Thanks for the files and sharing your methods bro, will do this when I'm free 

Anyways, do you think that this phone needs to recharge more often than other phones?
I figured out that the 3G signal when enabled is draining the battery a bit, so when I'm not doing any mobile internet'ing, I switch to GSM only, and now the phone needs recharging after more than 4 days...
