supl.nokia.com was working for me in California, but took a few minutes.
After switching to google, it's almost instant.

But supl.nokia.com gets a location closer to where I am. I'd be at 11642 magnolia st. and it would show 11644 or something like that. Which would be the house right next door

With google i'll be at 11642 magnolia st. and it'll show 11652 or around there. Which is 5 or so houses down.
