I have a similar problem, unable suddenly to connect to GPS. Here's the post I wrote a couple of hours ago. Would appreciate any help:

I'm having trouble connecting with GPS. Using Ovi Maps, I have been using supl.google.com with no problems until a few days ago. Now, I'm just seeing a box on maps stating "Looking for GPS...". I've tried re-booting, and going back to using supl.nokia.com . That suple.nokia.com entry gives me a coarse location, about a 1/4 - 1/2 mile away. However, I would like to have more accurate GPS location. I would appreciate if you could help me out here. If supl.google.com is still supposed to be working, what could have gone wrong with my using it? I didn't tinker with any other settings. And, as noted, supl.google.com had been working for me until very recently. Did google change something? Is there a different entry I should use? Thanks very much, in advance, for your help.
