In a way, I'm glad I'm not the only one... but in a way I don't feel glad, because this seems to be a huge, huge problem.
I'm also in New York State (around Rochester, but I drove between there and Syracuse today and it's effective everywhere). Nothing from Google Maps or Nav except for the "Coarse" location... which has me somewhere in the south of France!... and back again.
What's baffling is that GPS and the cell tower data should be independent of each other, yet other apps that ONLY use the GPS are effected by this too (GPS Test). All day long I could not get a coordinate mapping on that to come up either...
What I just tried: Leave GPS turned on, but go into "Airplane Mode". Then try any app that uses GPS only (like GPS Test). When I did this, I got my coordinates back. Then when I turned the network back on, I was getting Google Maps to lock on with GPS again.
HTC Weather still has me in the south of France, however, so I wonder how long this lasts...
I had tried literally every other fix before this, including reboots and a battery pull. What I don't get is, why should only Verizon be effected? Or with apps that only use GPS, why would the network matter at all?

And I still don't know if I stumbled on a fix, or just a temporary patch...
