no gps fix after satellite data outdated and phone restart

[Pop]

I've been using the accutracking software for about 4 weeks and it's been working well.

yesterday the tracking stopped working and i checked the phone and it was the "satellite data outdated" message. I dismissed the message and restarted the phone and accutracking seemed to be working fine, but now for the last 19 hours all i've gotten is a cell tower fix. The phone has been in an area where I've previously gotten a good gps fix so I don't know exactly what to do.

The first fix usually takes longer and requires better sky view. Just hold it for a while in one place with a good view of the sky.
