My iPhone 4 has several apps that I use location services on. But one set of 2 apps from the same developer will not show my location. They are enabled in Location Services, and show a grey arrow to show they have requested location, but will not provide a location on their maps. I have a GPS Status app which reports at the correct location, as does google maps etc.
The apps have been removed and re-installed. reboots of the hardware have happened. I'm wondering if there is a hardware fault, as the developer of the app reports no similar problems with iPhone users.
PS: iPhone 4 A1332 version 6.1.3 (10B329)
