My iPhone's GPS accuracy is poor when the WiFi is turned off. I did some tests yesterday and it showed me almost 1/2 mile away from my true location but with the WiFi turned on the accuracy was within 100 feet. The WiFi did not have to be connected to any network but the mere act of turning it on improved the GPS accuracy with the built in Google maps. I then read an article in an Apple support forum that confirmed this condition as reported by others.
