Thai language

[Guest Just Johnny]

Got myself a fancy new samsung galaxy s but want to be able to send and recieve thai sms from my friends kids. But the model here in Aust will not reconize it. All I get is little square boxes. I have put in an app that lets me translate thai - english and english - thai so I know it can display the charaters but it won`t let me save it to send as a message. does anybody know a way to install thai as a language option??

hope somebody can pleaqse help me..
