| had this problem with a 3gs 16gb, too. Before update to 4.2 the GPS works fine on the phone. After update nearly no GPS signal. Intern Kompass works very bad. This little symbol for GPS was also not to seen on screen.
I installed the firmware again, and after this it works with intern compass, and Navigon routeplanner.
PS. I dont need jailbreak or unlock for this phone, while it is providerfree. |
