UC Berkeley - When do we find out if our request to transfer dorms is approved?

My calcentral account just updated with the housing prices and it says unit 3, even though i put in a request to transfer to any of the other dorms on july 1, the same day that i was assigned unit 3. Does the fact mean that it says unit 3 on my account mean that Im locked in for unit 3??? I hope not. Also, does anyone know when we find out our roommates? Where do we find them? I was guessing on the housing portal, but idk. Any information is really appreciated!!
