My friend has a OOB 1.1.3 16GB iPhone (O2-UK).
He had already activated it on an official contract, and then used ZiPhone to unlock/jailbreak it.
Since then, and even though his Modem FW remains at 04.03.13_G, his google maps locator function has stopped working, UNLESS he does the LocateMe/Navizon fix every time he reboots/exits Airplane mode.
Any ideas why this might be happening? And while we're at it, has anyone ever actually explained WHY the LocateMe fix works?
