LocationFaker8 replaces GPS-sourced location data with a fake location chosen by the user. Once installed, the LocationFaker app will appear on the iOS 8 home screen. Locations can be searched, and a list of favorite spoofed locations can even be kept for later use.
While the fake location will be used by a majority of apps, some are more sophisticated and will not recognize the fake location. In any case, LocationFaker8 can be used to circumvent regional content restrictions or simply for fun. A White List of apps can be configured to make sure certain apps always use the real location.
LocationFaker8 is available from the BigBoss repository on Cydia for $2.99
