Hi everyone, as I am developing for iPhone, I've just bought an iPhone 4 to test my application which needs to measure the coordinates of my location. I don't have any Internet (3GS, GPRS or whatever...) on my iPhone and the problem is:
1) Without internet I get a 1744m horizontal accuracy, and that's very bad. (I've also tested the accuracy in other applications too, and it is always so bad or worser)
2) With WiFi-Internet I get a 80m horizontal accuracy.
Is that normal? What can I do to improve my coordinates-measurement accuracy?
Thanks in advance for any help.
