Tonight I disabled "use wireless networks" under the location menu. I let the regular GPS stay enabled. Shortly after, I noticed that my GPS icon was flickering insanely fast. It wasn't just the "searching" type of flash. It was super, super fast. Easily 15x a second. So then I go into settings and re-enable "use wireless networks" and it's fine. I disable "use wireless networks" and it goes insane again. I made sure I was signed out of Latitude, but even when I did that, it didn't matter. I thought maybe being signed in to Latitude was effecting it, but alas it was not. Has anybody seen this before? Anybody know what it means?
