The Apple iPhone 3G seems to be having a few problems, no really? Yes, especially with the GPS hardware apparently. The iPhone 3G’s GPS hardware gets into trouble when connected to the AT&T 3G network.
The guys at iPhone Atlas report that some iPhone 3G users are moaning about inaccurate GPS positioning when the 3G data setting option is turned on.
As most know, the iPhone 3G uses aGPS which is assisted GPS so means the mobile network aids in positioning the mobile handset and giving the GPS hardware less to deal with. This means super fast GPS lock on.
However, it appears that some iPhone’s are receiving conflicting data from the 3G data network and the built-in GPS receivers thus leading to incorrect GPS positioning.
So here’s a fix from the iPhone Atlas guys: Go to settings, general, network, enable 3G and toggle off. Next locate yourself using the iPhone 3G’s GPS receiver, and then go to settings, general, network, enable 3G and toggle on.
This should now make your iPhone GPS accurate. However, if it doesn’t work drop us a comment saying so.
