lol.. just mod or replace the phf_2_play.wbxml with the modded ones available on the internet.

find the one that suits ur taste.

I'm currently using SuperBassBoostMM,
checkout the download link in K850i thread.

if ur phone different, then no lar..

if wanna change acoustic, just change what u want only,
say loudspeaker, u change farfields files
if earphones, u chage phfs files..

no need to delete ur ori then put other,
coz like my c702 phone, got all together 56 wbxml files.
k850i got 55 files...

if slider phones, maybe more, coz got extra sound for sliding motion..

if u cut and paste bulat-bulat other model phone, ur phone might not produce sound..and it maybe not affecting slider only, there are cases where radio not working..

basically all wbxml file are same... the one different maybe ur hardware, if W705 got bigger speaker unit than other phone, sound maybe got different abit lah eventhough using same acoustics..

afterall, music is subjective.. some maybe like super duper bass... while some like clear with no hissing sound..

just try all acoustics out there..
