<Help!>Changing Language to Chinese Traditional C905

Can anybody please teach me any ways that I can change my SE C905 from English to Chinese Traditonal Operating system? Because it came with the contract and I would like to be able to use it in hong Kong. Are there any softwares or upgrades that I need to do?

Thank you very much for your help

Read this [Debrand] A2 (Db3150) Tutorial - Top Sony Forums .I think that should be work even on your C905
