Hi, What is the best way to search for GPS co-ordinates on an iPhone? I have the app which I find good but haven't managed to do any finds other than traditional as the app doesn't seem to allow a search on coordinates that are part of solving a multi or mystery cache. I've tried putting coordinates into google but always comes up blank. Does anyone know the best way to do this? PS - I don't have a GPS device, just my iPhone Cheers Geo__Kev
