    Has anyone noticed that the time to get a decent GPS fix on the iPhone 3G has gone way up?

    It now takes around 40-60 seconds to get a fix with a <100 m accuracy, even when outside. I believe the acquisition time was closer to 10 seconds just a few days ago.

    Can it be that AT&T is having issues with its A-GPS system? Perhaps the phone can't download ephemeris data from the network and needs to get it from the satellites? It is also possible that something changed in OS 2.0.1.

    I am in Seattle BTW. This could be a local problem.
