Before it would take a couple minutes for google maps to find the satellites, if we were driving in a car it would take forever untill we stopped moving.
Now, the version of google maps on the old rom is different than the one I just downloaded to my phone. In my house, in the room that I'm in, I'm away from two small windows, blinds closed and I have two large trees outside the window blocking the sky and the windows face north and west.
I click on "use gps" in google maps and it "supposedly" finds 8 satellites in a matter of less than 10-20 seconds.
It was my understanding that you had to be in direct line of sight with a satellite for gps, I know I dont have signal repeaters in my roof and I doubt that there aren't 8 statellites visible to the north.

Your old ROM must not have supported aGPS, which was mentioned earlier in the thread. With modern phones with aGPS support, the phone is able to lock with reasonable accuracy only 3 satellites. These satellite signals can even be bounced from nearby buildings so its possible to still get a lock indoors as long as you're close enough to a window. aGPS uses the surrounding cell towers to 'hint' the phone as to its approximate location.
