Is anyone else seeing issues with the GPS on 3.1? I have to reboot my iphone daily for it to work properly. If I don't reboot the GPS in google always shows me a 1/2 mile and don't catch up until I stop at a traffic light. Navigon will not even get a lock on my location. After I reboot it does great for about 24 hours. I am hoping it is a bug in 3.1 OS.
