Yesterday I couldn't get navigation to work because it constantly said "searching for gps...". Wound up clicking over some time last night and working fine, but this morning I was on the calendar and the phone restarted itself. This is the first time it has happened and I think I may have just hit one too many buttons simultaneously causing it. Once it restarted however, the weather widgets and gps no longer worked again. I never had a problem with it losing gps for the weather but it now reads "GPS Unavailable", instead of the temperature. I have turned the phone off and on again, checked to make sure I have the satellite turned on, and it's not coming back. Any idea what may be causing the gps not to work? Influx of new users this morning? Me? It also shows the satellite in the top task bar but still reads that it cannot locate a gps signal on my widgets.
