I also thought that my GPS was broken or something, 'cause it would never catch up with the satellite signal. But reading this 3d, I noticed that the "network based positioning" was disabled. When I enabled it, worked just amazingly...it gained the signal in 1 sec I think. And it worked offline. I just downloaded the all the maps I needed from the nokia map loader. It take some time, but works perfectly. Since now I feel very lucky, 'cause everything works the way it should on my N900. Even after the update, it' the best device I've ever had...way better than the iphone...
