Is the University Fellowship just for the first year and then you are back down to normal funding for RA/TAing?
By the way, many professors it seems haven't contacted the applicants who received the fellowship yet. So just because you haven't heard anything doesn't mean you didn't get it, so don't get discouraged. My friend just heard today after contacting the POI, who said he got it and they planned to send out the official letters next week.
