Hello.
To have Greek on Swype, extract the archive from the following link to "home/user/.swype/data". If the folder does not exist, create it.
Use this as a template for any other language you need. Languages can be extracted from Swype for Android, pay attention to the *.lst files, they need to list all the languages.
