Extract the gdr font file and put it into "c:\system\fonts" then restart your phone.

This font only works in opera mini (very well) and also in opera mobile (poor) but not in other browser and also not for any other application of phone e.g. Messaging.

This font can show hindi/marathi charecters used in orkut.
