Finally decided to flash to Chinese support version, RM100 fly

(SE sucks) cant do it outside as warranty will void
Went to Ericserve yesterday, waited for 2 hours and here are the extras :
1) able to read/write chinese
2) Chinese - English / English - Chinese Dictionary
3) Lunar Calendar
Firmware :
Phone: CXC 162037 R9H004
Bluetooth: CXC 162143 R1D
Organizer: CXC 162156 R6E30
CDA: 162024/95 R5A
Please note the followings before changing the firmware:
1) a back-up under the english software will not be able to be restored into the phone under the chinese software.
Synchronisation will not be affected though. So you might want to consider doing a synchronisation instead of back-up.
2) your phone will function slower as the chinese software takes up more RAM than the english software,
3) handwriting recognition of english letter might not be as sensitive and will take slightly longer to be registered.
4) the service centres after flashing the chinese software in for you will not be able to flash it
back to the original english version.
All my phone book (sim card phone book not affected) gone as I didnt synchronise, only do backup.
