I hope Google is not going to shut down this service like they did with this other one. After all they stole this data from us without letting us know about it so I see no reason why we shouldn't be able to use it now.
This app is fantastic. Just tested it side-by-side with a friend's stock 1.1.3 phone and it gave us identical coordinates. It's fast and a lot more accurate than Navizon. I REALLY hope they don't shut this down.
