About a week ago, I noticed that Gowalla was being very loose about how far away from a spot I could be and still check-in.
I opened Google Maps and saw that the blue dot showing my location wasn’t as accurate as it has been in the past. Here is a good example. Check out the image at the bottom of the post. The blue dot shows where the GPS thinks I am. The purple pin is where I actually was. It is almost like the iPhone has reverted back to basic cell tower triangulation, which is what the first generation iPhones use on the EDGE network.
I have found a few references in the Apple support forums about issues in the 3.1.2 firmware causing problems in the GPS.
I have also found a few fixes that rely on disabling certain services on the iPhone, rebooting, etc. The only thing I have not tried is a full restore of the iPhone back to the factory settings. I guess that is up next.
Anyone else having this problem on their iPhone 3G or 3GS?

This looks like the next generation GPS – where you should or would like to be instead of where you actually are. Take this as an example. You were at Babies-R-Us and… well… you know Mr. Wang’s has a seriously rockin’ buffet. That is where you should have been.
I have a 3GS as well and I’ve noticed for the past few weeks that Google Maps have definitely been less accurate than it used to be when placing my location. I just went to confirm this and the iPhone has my position a good 2-3 miles away from where I actually am. I also have practically no signal, so I guess I’m stuck in triangulation mode as well and not GPS.
hoping this iPhone update fixes the GPS issues I have been having recently (http://bit.ly/9yhtBY)

I was having the same issue, at Church of the Highlands it wouldn’t let me check in inside the church (or on the side walk) only the parking lot.
Same problem with no fix on GPS with 3.1.3 on a not jailbroken iPhone 3GS. Maps does not show GPS blue dot fix, my Navigon Nordic is useless. Reboot does not help, disabling data does not help.
So i tried to figure out what s causing the problem
1. Normal reset with restore from previous backup did nothing
2. Full reset to Factory default, everything work perfect, i then waited with new installs untill next day and both Maps and Navigon are working
3. Started to install all my bought apps, waited for day again…Maps and Navigon are working
4. Installed the all new WordPress 2 client…GPS dead…Maps and Navigon are useless again
5. Uninstalled WordPress 2, no change…GPS still not working
6. Reboot does nothing
7. Full reset to factory defaults….everything is working again
8. Installing all paid apps …reboot and testing GPS in both Maps and Navigon after every installation
…works perfect
9. Installing WordPress 2…GPS again useless
…anyone else having that problem???
So are you saying that the WordPress2 app may be the culprit? I have it installed.
