HR10-250 recently activated, not upgrading to 6.3

I activated an HR10-250 that has been inactive for a few months. It's been active with a phone line (forced calls work, normal calls work) for 10 days. I am still waiting for 6.3. What needs to happen before it upgrades? Also, does 6.3 help with audio over HDMI? Not working with my new Sharp LCD with HDMI 1.3.

thanks...joe
