That font *might* be installed with an OS version that supports the Dravidian language. If it's available at all it would be through an Indian carrier. If not, I don't think you can get that font.
I saw in my 9900, it says you have to connect to your desktop/laptop and install under languages... not sure it talks just about the languages exists already or we can add there.. anybody tried this ever?.. if yes. please let me know..
