Is it possible? I know there are programs out there to change your phone code and so on... but will any of this help me with my quest to have the normal APAC version of the firmware for the N93? That is, I'd like to have English/Chinese input support on my currently European-firmware (Eng/French/German/etc...) N93. I'm hoping the NSU (when it becomes available again) will help too.
Changing f/w from European -> APAC (Eng/Chinese)
It is possible. You can flash it yourself, but that voids warrenty (so the officials say). You can also change your product code quite easily with software called NSS. Then you need to wait for the new firmware to become available on the NSU. If you have changed your productcode, the NSU will update the firmware to APAC version.
