Yes. Without AGPS is very slow. To get a lock on my n900 I have to wait about 7minutes minimum and usually even more. And I tested this not from inside a building but from outside where there were no buildings near me so it should be fast. And in GPSjini I can see that it found about 10 or more satelites and the signal on 5 of them is 100% but still it does not lock. I can not understand this.
