Have you contacted your carrier (EE, O2, etc)? They would be best suited to answer that question.

Whose firmware do you currently have on it? It may be carrier unlocked but you have to have someone's ROM loaded - I'd assume that you're going to stick with the same carrier?
The GT-i9300s already seem to have 4.3 firmware available...

Sorry, you're just going to have to wait until the carrier releases the 4.3 update.
